I have a WPMU site installed: http://PleiadesServices.com which has been up and running since vers. 2.6.1. My main site is fine, but all the blogs are gone - I just get a generic 404 ( I was on vacation, so I'm not sure when it happened, but they were last updated 5/4/10 ).
WPMU is installed in root. LAMP install:
Linux
Apache/1.3.33
MySQL 5.0.91-log
PHP Version 5.2.5
Here is my attempt at diagnosis:
1. phpMyadmin shows all the tables exist and have content.
2. there was no htacces file in root, so I renamed htaccess.dist to .htaccess - that resulted in 500 Internal Server Error, so I renamed back to .dist and got my generic 404 again.
3. went into permalinks and changed to date and time - no change
4. changed to default permalinks - no change
5. ran Site Admin --> Upgrade. Ran successfully but no change.
6. called the hosting company. No mods were done to servers or configs.
7. checked the forum - looked at topics 15978, 14503, 17593 - tried experimenting with versions of htaccess based on forum - all result in 500 error.
8. Tried most basic possible htaccess file:
RewriteEngine On
RewriteBase BASE/
Got the 500 error again.
9. When to Admin --> blogs and edited blog and saved options. Still can't visit or edit backend - 404.
10. Give up and write this post.
Really need help. Any suggestions, please?
