Internal Server Error

[saith]

I can't access to my gallery at all since today I think (URL : http://legacynjo.com/fr/gallery/) . The last time I had changed something was months and months ago and my last picture upload is old as well. The following message appears:

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

Please contact the server administrator, postmaster@www.legacynjo.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.

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

I'm hosted at OVH and everything else on my website is working, I even have another working coppermine gallery, wich by the way is the exact copy of the one wich is not working exept for the langage (URL : http://legacynjo.com/en/gallery/).

The version on both gallery was Coppermine Photo Gallery v1.4.12. I tried updating the one wich doesn't work to v1.4.19 but nothing happened (I get the same error when opening http://www.legacynjo.com/fr/gallery/update.php)

Is there any way I can repair my gallery ? I'de be really greatfull if someone could help me figure this out.

Thank you in advance

Read the error log as suggested. If that doesn't help you then you need to ask your host what the problem is.
