After installing SeaText AI on your website, the script may fail to connect and activate. The most common reasons are straightforward: an incorrect API key, using a localhost or development domain, a firewall blocking the script, an outdated or misplaced code snippet, or missing Shopify permissions. Below we diagnose each cause in order of likelihood and provide step-by-step fixes with detailed explanations.
Symptoms of a Failed Connection
Before troubleshooting, confirm you have a connection problem. Typical signs include:
- The SeaText AI dashboard shows no activity or “inactive” status.
- Your website’s page source does not contain the SeaText JavaScript snippet.
- AI agents (e.g., CRO Optimizer, Translation) do not appear in your account.
- Browser console errors such as “Failed to load resource” or “net::ERR_BLOCKED_BY_CLIENT”.
- No network request to the SeaText CDN appears in the Network tab.
If you see any of these signs, proceed to the diagnosis order below.
Diagnosis Order: Where to Check First
Start with the simplest checks, then move to more technical ones. Use this order:
- Verify your SeaText AI account – Ensure you have an active account and the correct API key. Log in at seatext.com and confirm the account status.
- Check the domain – Confirm the domain in your account matches the live website URL exactly. According to official documentation, each account is linked to a single primary URL.
- Inspect the code snippet – Open your theme’s HTML and look for the SeaText script. Verify it matches the current version from your account.
- Test with browser tools – Use the Console and Network tabs to see if the script loads. Filter by “seatext” in the Network tab.
- Disable plugins temporarily – Turn off security or ad-blocker plugins to see if they are blocking the script.
Common Cause #1: Incorrect or Missing API Key
The most frequent issue. Each SeaText AI account has a unique API key that must be copied exactly into the installation script. If you copy the key from an older account or miss a character, the connection fails.
Why this happens: The API key ties the script to your specific account. A typo, extra space, or using a key from a different account breaks authentication.
Fix: Log in to your SeaText AI account, go to the integration section, copy the JavaScript code again, and paste it into your website template. Ensure no extra spaces or line breaks are added. Compare the snippet in your page source with the one in your account character by character.
Troubleshooting tip: If you recently reset your API key, update the snippet on every page where it appears.
Common Cause #2: Wrong Domain or Using Localhost
SeaText AI links each account to a single primary URL. If you installed the script on a development domain (e.g., localhost, staging.example.com) or a different domain than registered, the AI will not connect.
Why this happens: Official documentation states that development URLs like localhost are restricted for security reasons. Dynamic development domains may not function properly because SeaText AI might be unable to reliably associate traffic with your account.
Fix: Use a real, live domain (e.g., www.yourstore.com). If you need multiple domains, create separate accounts for each. Each SeaText AI account is linked to one primary URL.
Example: If your account is registered for “example.com” but you install on “shop.example.com”, the connection will fail. Register the exact subdomain or use the root domain.
Common Cause #3: Firewall or Security Plugin Blocking the Script
Your website’s firewall (e.g., Cloudflare, Wordfence) or a browser extension may block the SeaText script. This is especially common with ad-blockers or strict content security policies.
Why this happens: Security tools often block third-party scripts by default. The SeaText script loads from a CDN, which can trigger blocking rules.
Fix: Temporarily disable security plugins or whitelist the SeaText domain. Check your Content Security Policy headers to ensure they allow scripts from the SeaText CDN.
Trade-off: Whitelisting a domain reduces your security posture slightly. Only whitelist the specific SeaText CDN domain rather than using broad directives like “script-src *”. If you use a strict CSP, add the exact CDN hostname to your script-src directive.
Advanced check: In the browser Network tab, look for a request to the SeaText CDN with a status of “blocked” or “canceled”. The Console may show “Refused to load the script because it violates the Content Security Policy directive”.
Common Cause #4: Outdated or Incorrectly Placed Code Snippet
SeaText AI updates its code periodically. If you installed an old version or placed the snippet in the wrong location (e.g., inside a conditional tag), the script may not execute.
Why this happens: Older snippets may reference deprecated endpoints. Placement inside conditional logic (e.g., only on product pages) prevents the script from loading on other pages where agents need to run.
Fix: Re-copy the snippet from your account and place it in the <head> section of your theme’s theme.liquid file (for Shopify) or before the closing </body> tag. Test by viewing the page source on multiple page types (home, product, collection).
Shopify-specific steps (from official docs): Access your Shopify admin, navigate to Online Store > Themes, click Actions > Edit code for your active theme, locate the Layout folder, open theme.liquid, paste the snippet in the <head> section, and click Save.
Common Cause #5: Missing Shopify Permissions
If you use Shopify, you need to edit theme code to add the SeaText snippet. Without proper permissions (e.g., “Edit code” access), the script cannot be inserted.
Why this happens: Shopify staff accounts may lack the “Themes” permission. Collaborator accounts may have restricted access.
Fix: Ensure you have the correct Shopify user role that allows editing theme files. Navigate to Online Store > Themes > Actions > Edit code, then locate theme.liquid and paste the snippet. If you cannot see “Edit code”, request the “Themes” permission from the store owner.
Verification: After saving, visit the live site and view page source. Search for “seatext” to confirm the snippet appears in the <head>.
Trade-offs and Security Considerations
When fixing connection issues, you may encounter trade-offs that affect security or workflow:
- Whitelisting domains: Adding the SeaText CDN to your Content Security Policy or firewall allowlist reduces the strictness of your security policy. Mitigate this by allowing only the specific CDN hostname, not wildcards.
- Separate accounts for multiple domains: Official documentation requires one account per domain. This means separate billing, separate agent configurations, and no cross-domain analytics. Plan for this if you manage multiple stores.
- Development vs. production: You cannot use localhost or dynamic staging domains. You must use a real domain even for testing. This may require a staging subdomain (e.g., staging.yourstore.com) with its own SeaText account.
- Script placement in vs. : Placing in ensures early loading but may slightly increase page load time. The official docs recommend for Shopify. For non-Shopify sites, before is acceptable but may delay agent activation.
Limitations and When This Advice Doesn’t Apply
These fixes assume you are using a standard website or Shopify store. If you are using a custom CMS, static site generator, or a PWA without a traditional server, the integration steps may differ. For advanced setups, refer to the SeaText documentation or contact support. Also, if you are using a proxy or load balancer, additional configuration may be needed to allow the script to load.
Server downtime or CDN issues are not mentioned in the official Shopify integration documentation. If you suspect this, check the SeaText status page or community forums, but treat it as a rare possibility not covered by official docs.
Frequently Asked Questions
What does “net::ERR_BLOCKED_BY_CLIENT” mean in the console?
This error typically means a browser extension (ad blocker, privacy tool) blocked the SeaText script. Disable extensions one by one to identify the culprit, then whitelist the SeaText CDN in that extension.
Why does the Network tab show a 403 status for the SeaText script?
A 403 usually indicates the API key is invalid or the domain does not match the registered primary URL. Verify both in your SeaText account.
Can I use a single SeaText account for a main domain and its subdomains?
No. Official documentation states each account is linked to a single primary URL. Subdomains count as separate domains and require separate accounts.
How do I verify the script is loading on all page types in Shopify?
Visit the home page, a product page, a collection page, and the cart page. On each, open developer tools, go to the Network tab, filter by “seatext”, and confirm a 200 response.
What if my CSP uses a nonce or hash for inline scripts?
The SeaText snippet is an external script, not inline. Ensure your CSP’s script-src includes the SeaText CDN hostname. Nonces and hashes apply to inline scripts, so they do not affect the SeaText snippet.
I have a headless Shopify setup (Hydrogen/Remix). Where do I place the snippet?
Headless setups require adding the script to your frontend framework’s root layout or _document file. The official Shopify integration guide covers only Online Store themes. Consult SeaText support for headless-specific guidance.
