It took some time to test it but all I got from the error report is a repeating
Strict Standards: Only variables should be passed by reference in C:\xampp\htdocs\tinyjfj\jupgrade\components\com_comprofiler\plugin\user\plug_cbconditional\cbconditional.class.php on line 743
Strict Standards: Only variables should be passed by reference in C:\xampp\htdocs\tinyjfj\jupgrade\components\com_comprofiler\plugin\user\plug_cbconditional\cbconditional.class.php on line 744
and at the end is
Fatal error: Maximum execution time of 30 seconds exceeded in C:\xampp\htdocs\tinyjfj\jupgrade\components\com_comprofiler\plugin\user\plug_cbconditional\cbconditional.class.php on line 744
I tried removing the conditions on the fields one by one and checking the page for any result. After removing conditions to a few dozen of fields, the page started to render, still having the "Strict Standards:..." on top of it. I continue removing conditions from the remaining fields and as a result, the repeated error message being displayed becomes lesser and lesser. After removing all the conditions to all the fields, the page now renders properly without any error messages, but all of my fields now doesn't have any conditions to them.
