PHPBB problem login

Hi, I have a problem with the forum taking my log I get a blank page? and I do not charge himself a forum asking for your help?

Well, the first thing I’d try to do is Google the error to see if someone else has got the same issue and solved it. You could also try to see if you can enable some kind of debug mode which may give you more information about what’s going wrong or give you a clear error message you can search more effectively for.

I’m not a phpBB expert so I can’t tell you anything about phpBB specific issues.
