OK, I found out what’s wrong!!

I’ve tried a couple of things to isolate the problem:
-Deactivated all plugins => same error message
-Switched from Thesis to the default theme => no error message!
-Reactivated all plugins while using the default theme => still no error message
-Switched back to Thesis => old error message back again => something in Thesis causes the problem

I then made a backup of the custom.css and custom_functions.php files. Next, I deleted the entire code in both files (in the custom file editor). => error message gone!!

I experimented with the code of both files (deleting parts of it here and there to find out what caused the problem) and figured out that there was something in custom_functions.php file. In the first line, there it was: “?<?php”. Deleted the first question mark and everything is running smoothly now. Don’t know if the first question mark was there from the beginning or if it somehow slipped in there, but that was the little bug that caused the mess…

Thanks for your support,
Tom
