I have two gibbon installations on the same server but two subdomains and separate unique guid keys, problem is one was working but now giving me a fatal error while the second gives a blank page. Please check at:
Steve, it seems each install has a separate setting for displaying errors, with one showing errors, and the other not. Different php.ini settings, or different settings via .htaccess perhaps?
I had one php.ini file in the root directory but after i deleted it the first site works well now. The second one is still blank. I wonder why.
Steve, for the second site, can you try and turn on error messages in PHP, so we can see what the error message is?
