"0 - syntax error, unexpected end of file" after transfering my site to another hoster

Question

I recently transfered my domain from strato to netcup. I installed a fresh joomla 4 and installed my template (custom written).

The Issue is I get the error: "0 - syntax error, unexpected end of file" on my main page. I've tried the same on the old server (because its still active) and it's working fine. This tells me that it's some configuration / PHP issue but I can't figure out how to fix it.

The stacktrace reads as follows:

Uncaught Throwable of type ParseError thrown with message "syntax error, unexpected end of file". stack trace: 
#0  [ROOT]/libraries/src/Dispatcher/ModuleDispatcher.php(52): include()

If someone has an idea please help. Thanks in advance.

Answer 1

The option short_open_tag = "1" has to be set like that. For some reason the server had set it to 0 by default.
