If nothing works then maybe it is the problem that I faced.
– Upgraded to WordPress v 2.8.1 – no problems before that
– Tried to change permalinks and got all these unsolvable htaccess errors
– Even deleted the WP installation and everything and reinstalled but same problem
– Got a brainwave – Thank God!
– Went to WP Settings -> General, changed the default settings for BOTH URL areas to point to simply http://www.mydomain.com
– Permalinks working again !
– Actually I am using the ‘add domain’ feature to host multiple domains in a single account in bluehost. So the default in WP settings points to http://www.basedomain.com/mydomain which dosen’t work.
– Trust that helps someone.
I waited 2 days, posted on their site, wrote to them, installed it many times over. No answer.
Tried Disqus, it did install fine, its good – but did not meet a couple of my requirements. Finally using the very basic ‘Subscribe to Comments’ plugin. If you want to use it for WordPress v2.7, there is a modification to do, let me know.
