Since we needed GD support for captcha, I installed the entropy.ch build of PHP 5.2.5 in place of the default build installed by Apple on 10.5 Server.
After this, everything works fine through the rest of the site, but all EE pages are blank. Safari complains of an encoding error. FF shows blank page.
Can someone help me figure out what is going on?
Oh yea, no error in logs.
