I have been running my website for the past few months and don’t recall receiving any technical issue emails from WordPress in the past. Today I got an email from WordPress that I should fix an issue on my site as it could be a fatal error. The error is:
Error message: Uncaught TypeError: call_user_func(): Argument #1 ($callback) must be a valid callback, first array member is not a valid class name or object
The plugin this error is being reported in is Really Simple SSL. I don’t understand how I should fix this because I don’t remember doing anything recently that could have caused it. I was also given the Stack Trace for the error but I don’t know how to utilise it. If anyone can help me in any way, I would be very very grateful.
Regards
I have tried looking into my files but I don’t understand what I need to fix to solve the issue
Might want to try reaching out to Really Simple SSL’s support team for assistance with this: wordpress.org/support/plugin/really-simple-ssl
