Forbidden access

Hello,

I am using SmartSearchWP version 2.7.3 on a WordPress website hosted by OVH with Divi builder theme.

I have successfully configured my OpenAI API key and added API credits. The key is validated correctly by the plugin.

Current status:

• OpenAI API key is valid
• OpenAI billing is active
• Contexts are generated successfully
• Pages are trained and marked as active (green status)
• REST API is enabled and working (/wp-json/ loads correctly)
• The route /wp-json/wdgpt/v1 is registered correctly

However, the chatbot does not work.

When a visitor sends a message, the request:

POST /wp-json/wdgpt/v1/retrieve-prompt

returns:

403 Forbidden

Response:

<title>403 Forbidden</title>
<h1>Forbidden</h1>
<p>You don't have permission to access this resource.</p>

Additional information:

• Hosting: OVH
• CDN: OVH Basic CDN enabled
• WP-Optimize cache disabled during testing
• Permalinks refreshed
• Context generation works correctly
• Only chatbot requests fail

In Chrome DevTools, the failed request is:

https://domainedesclauzes.com/wp-json/wdgpt/v1/retrieve-prompt

Status code:

403 Forbidden

Could you please advise what could cause the retrieve-prompt endpoint to return a 403 error while context generation works correctly?

Thank you.
