500 error

[Gideon V]

Hello,

Our forum is offline for a few weeks now. When going to the forum there's a 500 error. http://mobbles-forum.com/.
I did not made any changes to the forum. It just happened all of the sudden during the holiday.

I asked my host to look at it, but he was not able to find any problems. He asked me if I could emty the Cache but I can't even access the admin page anymore.

Does anyone know what we could do to fix this?

Kind regards,
Gideon
