Disable all your plugins/products/modifications and try using a default style and see if you get problems.

I have Disable all plugins/products/modifications :
define('DISABLE_HOOKS', true);
but return this error:

Fatal error: Call to undefined function: print_portal_output() in E:\wwwroot\forum\index.php on line 48

I don't want to exclude all mods installed in years of work
I have not installed new add-ons or plug-in in the last days
and the forum worked well up to yesterday
