I have been experiencing some critical errors with this website and on investigation, it appears that the Error_log in my Cpanel File Manager is packed with thousands of errors which appear to relate to the GP Theme.
First thing I tried is swapping GP theme to WordPress Twenty Twenty One theme. When I do, the errors stop. When I activate GP or my Child theme, the errors come back.
I have attached a line from the error log. Please could you advise what could be causing this.
Yes, I had tried everything you suggested without success, however I just completely deleted GP and re-installed a new one and the errors appear to have stopped. Not sure what happened, perhaps the Database wigged out at some stage and corrupted the theme. Anyway, seems OK now, so I will monitor. Sorry to waste your time David.
