I need some help troubleshooting - I've searched and read a lot throughout this forum but can't seem to find an answer, so here goes:
I have two installs of WP on my site. The newest one, currently under development, is with WP 2.5. Problem is, the site frequently bogs down and essentially refuses to load any pages. Then, sometime later, it comes back to life and I can get a little work done, then it goes bad again.
site is here: http://www.heraldleaderphoto.com/derby/2008
Here's what I know: The server is running PHP 4.3.2. Don't know much else about it (I don't have good access to it since it's a corporate thing. They're not much help - I have to figure a lot of this stuff out myself)
The best I can get from an error log is this: undefined entity at line 289, column 67, referer: http://www.heraldleaderphoto.com/derby/2008/
But I can't seem to find anything wrong there and it's the same message on four different post pages that I've tried to access when it locks up.
I've reinstalled WP 2.5, but I have not tried to downgrade it yet. The other install of WP (2.3), which is on the same server, is working fine.
Anyway, any help I an get with troubleshooting would be much appreciated. Be aware I might need some details in your suggestions if they get overly technical.
