Hi,
I’d like to share my ideas with you all. I’m using Apache 1.3.34 with PHP 4.4.2 and WordPress 2. Spend a couple of days trying to figure out the blank page/output issue after login in. Two things I noticed, If I comment out the gd extension, and restart Apache, I’m able to login and see/add plugins fine which is kinda odd. Secondly, I notice Apache’s HARD_SERVER_LIMIT was set to 1024. I had to recompile it with the default limit of 512 and now it seems to work with PHP extensions enabled. If you have alot of extension enabled, try commenting them one at a time and see if it solves the problem. Also try lowering Apache’s hardlimit to its default if you have it tuned up.
