[Error]Service Temporarily Unavailable

[Lan-Di]

Hi,

I keep getting this error when i try to send a specific user here a PM or email. I get the same error whenever i want to reply on an old topic ( like 2 - 3 months old ).

How can i fix this?

What i tried:
PM, email and post with Firefox 8
PM, email and post with Firefox 8 in 'private browsing' ( no cookies )
PM, email and post with Internet explorer 8

Exact error:

Service Temporarily Unavailable

That error tends to occur when posting something containing a lot of images and URLs like I've noticed before;

The problems lies with the webserver although my webhost claimed that the 503 error is too generic to find any actual cause for it. I did some maintenance on the database but it's doubtful if it makes any difference.

Thank you for the info.
