Good evening,
Pardon me if this question is not in the right forum for Joomla support.

I'm working in a hosted environment where i had Joomla 3.8.5 running kinda unattended. When logging into my hosting CP, i noticed php versions were marked as 'obsolete', so i picked the version closest to what i had (not the latest/max available -- which is 8.1.4. When i chose this, my site crashed of course. I first toggled the various php versions available, but nothing resolved the issue. I then found and uploaded the 4.1.0 Update package, and seems to make some progress. I landed on a page where i was told php 7.2.5 min was required. As i landed on the suitable version of php in my CP, i had other php errors in the browser that led me to upload the FULL 4.1.0 stable package. This is where i am now.
I did check permissions on the file ComponentHelper.php and found them set as 755, i tried as 777, but no difference, so i am doubting this file is root cause. Any ideas on troubleshooting this?

Thank you,

WH
