I have WordPress (3.0) multisite installed (and correctly configured according to the WordPress 'Create A Network' tutorial) in the root of an add-on domain with two sites created using the subdirectory method of network install.
My site structure is as follows:
ADDON DOMAIN: http:/example.com/ (wordpress install location)
SITE 2: http:/example.com/site2/
SITE 3: http:/example.com/site3/
I have been getting random Internal Server Errors every now and then which disappear after waiting a few minutes and visiting each site again.
I have a suspicion that the cause of this could be something to do with either the .htaccess file (in the root directory of the add-on domain), or a redirect issue to do with the wp-config.php file. All generated mod_rewrite rules were added to my .htaccess file above /* That's all, stop editing! Happy blogging. */. HostGator is my host.
Any help would be much appreciated!
