Hi friends, sometimes after a post you could see this error message:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, 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 made some test and it seems that the problem is due to Posy that hangs the whole server ... It doesn't happen every time... But your post will be written anyway, so don't post it twice (or more). I'm lurking the gurus' forums in order to solve the problem... Sorry for the inconvenience...
