Rank Math and Masterstudy conflict

    Hello. I use Masterstudy LMS. When Rank Math is activated the user-account page in MS is crashing only in the WPML translated versions of the page.

    So e.g mydomain.com/user-account page is working but mydomain.com/de/user-account is not.
    Other pages work fine in all languages.

    This happens when RM is activated. I downgraded RM and WPML but nothing seems to solve the issue.

    Any ideas?

    Hello @more2think,

    Thank you so much for getting in touch.

    Could you please check if any errors are displayed on the affected translated page? If so, kindly share a screenshot of the error so we can take a closer look.

    Additionally, please go to WP Dashboard → Rank Math → Status & Tools → System Status, click the “Copy System Info to Clipboard” button, and paste the information here. This will help us further analyze the issue.

    We look forward to your reply.

    Hello Jeremy,
    Thank you for replying. I have noticed that I have the same issue on all my sites and some on different servers. All errors happen only on the translated page User Account. The English version is fine.

    The console does not show any errors. However, I use Bug Monitor and I found the following errors. I don’t know if they are related but I am posting them anyway.

    Error 1:

    A PHP error was caused by a WPML Multilingual CMS file

    Hello @more2think,

    From the error log you shared, the PHP error is originating from WPML where method_exists() is receiving an array instead of an object/string, which is what triggers the crash. Since this happens inside WPML’s code, it indicates a compatibility issue triggered when our plugin are active.

    We will need to check this further on your site. Please email our support team at [email protected] so we can assist you further.

    Looking forward to helping you.
