XFileSharing Pro - Need help with installation and setup

[lepotec]

Hi,

I installed XFileSharing Pro on a fresh Ubuntu server. The installation went smoothly, and all checks from install.cgi were green.

I managed to log in as a admin and create a file server. Uploading works normally, but I have a problem when clicking the download link.
When I try to open the download link, I get the following error in the browser:
Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator at webmaster@localhost 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.

Apache error logs return:
[Thu Feb 06 08:54:51.410932 2025] [cgid:error] [pid 506903:tid 123407442118336] [client 192.168.177.33:50051] malformed header from script 'index.cgi': Bad header: X

index.log in cgi-bin folder also contains:
[Thu Feb 6 09:47:37 2025][643444] [Thu Feb 6 09:47:37 2025] index.cgi: Built-in function 'builtin::blessed' is experimental at /usr/share/perl/5.38/File/Copy.pm line 58.


I also have a problem saving settings in the admin panel. If I try to change and save any settings, I get the following error:

Error
invalid license_key
XFilesharing Pro by Sibsoft Ltd

Even though the license key should be correct and the check during installation was successful.

I would be grateful for any tips or help.
