Which PHP version is used on the web space?
The admin area works with the index.php file and requires PHP, so the problem is most likely with the PHP version used on the web space.
If the PHP version is not known, ask the web hosting provider.

Version 8 of PHP
I don't get this error, neither on the test website nor on my real website, see
Test website >> http://finde-links.de/123shop-hosteurope/admin
I am at Hosteurope.de and have a normal web hosting package and PHP 8.1 is set there.
Either set it to PHP 8.1 or try an older PHP version.
Otherwise, wait for the moderators or Incomedia staff (during European office hours).

I turned the verbose result an I get this now:
Fatal error: Unparenthesized `a ? b : c ? d : e` is not supported. Use either `(a ? b : c) ? d : e` or `a ? b : (c ? d : e)` in /home/iotsnvtq/NailsByJelly.com/res/x5engine.php on line 5720
Any ideas?

Attached is screenshot of line 5720
For me, line 5720 in the x5engine.php file looks different, see

Maybe the moderators or other users can take a look at what you see in line 5720.
Hello; Before I modify the php file of your capture...
Have you tried using a different version of php, 7.4, 8.1 or 8.2? If the hosting allows it.
This depends on the version of wsx5 you use.
I remember that some users solve the problem by deactivating the display_errors box in the php options.
Try and comment.
