Hello BrianPx,
I am really sorry that you are still dealing with this frustration.
Do you have access to ftp? You can view permissions through most clients, FileZilla is one such client that makes it easy to see both owner and permissions. These are very important, so we need to make sure they are correct.
If you are able to check those and they are correct, then let’s move on.
————————————————————-
Let’s back up a bit.
If you return your folder to default location, and that’s all, you should still get the same message. So do that, and if the same message appears, then good.
Next keep the folder in the default location and update the two files. (index.php and admin.php)
Then test. This should return no errors. If that is true, then good. We are back at baseline. If you do get an error, then there is something else going on. At this point please report back here and tell us what you find.
From the baseline make the changes again, move the folder up one directory and update the two files again.
Let me know what you see.
Cheers,
