Chatbot broken since 2.8.9 – ‘session expired’ error, 2.8.8 works fine
-
Hello,
Since version 2.8.9, the chatbot stopped working completely. It shows this error in the browser console:
“Your session has expired. Please refresh the page to continue using AI Engine.”
Request fails with:
POST /wp-json/mwai-ui/v1/chats/submit → 401 (Unauthorized)
✅ What I’ve Tried:
Cleared all browser, plugin, and server caches
Disabled LiteSpeed Cache
I do not use NotificationX
Tried logged-in and guest users🔁 Version Behavior:
✅ 2.8.8 (Free) → works fine ❌ 2.8.9 and 2.9.0 (Free + Pro) → brokenI recently subscribed to Pro but had to downgrade to Free 2.8.8 to keep the chatbot working while waiting for a fix.
Here’s a screenshot of the error:

Can you help investigate this? Thanks!
Simon
