I've had to migrate my WP Network from one server to another (both are internal and not hosted by external companies). After following what I believe are all the necessary steps (backing up, copying, search/replace in DB, changing wp-config.php) all I see when I browse to my new domain/server is a blank page.
Just to describe the process in a bit more detail:
- I installed LAMP on new server (CentOS)
- Installed phpmyadmin
- Backed up wordpress installation via ftp & tar
- Backed up db
- Updated domain in database via search&replace
- Moved wordpress installation to new server via unix tar command
- Uploaded db via phpmyadmin
- Edited wp-config.php
And now I see a blank page.
Just to make matters worse, I now see a blank page on my existing server too, though this seems to have triggered later. I've gone through my unix command history and other than tarring files across from one server to another, I haven't done anything that 'touched' the wordpress installation.
I've tried the renaming plugins trick but to no success. Also, the back end on my new server doesn't seem to work either and the error message displayed reads,
ERROR: Unknown error in LDAP Authentication.

Thanks in advance!
P.S. I've searched a whole afternoon before posting this
EDIT: Might be worth adding that I'm allowing ports access individually on the redhat firewall, so far only 80 (virtual host), 21, 22 are allowed.
