LimeSurvey version: limesurvey6.10.0+250106
Own server
==================
I Installed LimeSurvey CE on my server on January 06, 2025. I sent a few surveys since. Today, I cannot access the admin page. In the browser, I get this error message:

Internal Server ErrorThe server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator at webmaster@survey.tld.org to inform them of the time this error occurred, and the actions you performed just before this error.

More information about this error may be available in the server error log.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.


The server error logs shows this:

[Sat Jan 25 19:26:58.095873 2025] [core:error] [pid 5296:tid 5378] [client ***.***.***.**:34248] End of script output before headers: index.php, referer: www.survey.tld.org/

I have no idea why I cannot access the admin page anymore. Would someone have a solution? Thanks!

Not related by LimeSurvey. Apache with userPHP or something like this

You must fix this via server configuration (ask at your server help forum)
