Conflict Between AI Engine and The Events Calendar Causing Server Error

    Hi,

    I am reaching out regarding a technical issue I encountered while using the AI Engine plugin on my website.

    When attempting to create or post content through AI Engine, I consistently receive a “Server Error”. After extensive troubleshooting, I discovered that this error only occurs when The Events Calendar plugin is active. When I deactivate The Events Calendar, AI Engine works normally, and posts are created without any issues.

    Upon enabling WordPress debugging, I found the following notice in the PHP error logs:

    Notice: Function register_rest_route was called incorrectly. Namespace must not start or end with a slash. Instead namespace ‘mwai-ui/v1/’ for route ‘/openai/realtime/start’ seems to contain a trailing slash.

    Fixing this would greatly improve compatibility with other popular plugins like The Events Calendar.

    Also, in the meantime, do you know of any workaround I could use to avoid this conflict without disabling either plugin?
    For example, is there a setting I could tweak in AI Engine, or a snippet I could add to temporarily patch it?

    Thank you very much for your attention and support.
    Please let me know if you need any additional information or server logs to help troubleshoot this further.

    Sam

    however, I want to mention that this register_rest_route notice might be irrelevant, and the real cause of the server error might be elsewhere. I just wanted to provide all the information I found during troubleshooting.

    Hey @samicai! 👋

    We are not aware of any incompatibility with Events Calendar. When you receive a “Server Error” message, make sure to check your network inspector and PHP error log to find the root of the issue, without this information, it can be hard to pinpoint the exact cause.

    Also, the messages you’re seeing are not actual errors but warnings intended for developers about best practices when declaring REST routes in the plugin code. You can safely ignore these messages, as they won’t impact your use of the plugin.

    Hey @valwa ,

    Thank you for your quick and helpful reply!

    You are absolutely right — the REST route warnings are not critical errors, and they can safely be ignored.
    After deeper investigation, I checked the PHP error logs as you suggested, and I found the real cause.

    It seems the issue is indeed related to a conflict with The Events Calendar plugin when trying to post generated content via the AI Engine “Content Generator”.

    From what I can see, the error is triggered at the posting stage, not during the generation of the content itself.

    I hope the attached logs will help you pinpoint the interaction issue more precisely.

    Out of curiosity, have you tried running both AI Engine and The Events Calendar plugins together on your end to see if you can reproduce the issue?
