500 Internal Server Error. How can I fix the problem?

[Torreto]

This is what I can see in the logs:

The site itself is working fine, but when you add news and uploading images, gets 500 Internal Server Error.

Please tell me what could be the problem?

Have you tried checking the disk space?

Check the permissions.

Should be 644 for the files
755 for the folder
The files and folders that you want to record, should have 777 permission.

Maybe this can be useful:

The chown -R the apache: the apache / the var / the lib / nginx could Fixed error
Reboot the server.

The chown -R the apache: the apache / the var / the lib / nginx partially fixed the bug.

But still facing problems with images. not able to uploaded them the server.
