I almost convinced myself that I was included in the list of people who “tried everything” to uninstall. After going through two pages of google searches on how to uninstall the plugin, I sat back, took a deep breath, and just thought for a second.
I then browsed around my site directories via ftp and found a second .htaccess file a level up from the wordpress installation. I had overlooked this one because I had already removed the WT3 additions from the .htaccess file in the wp install directory. Turns out that this one was a WT3 addition as well, and my wp was fixed after I removed those additions.
Overall, it was a VERY easy fix, but it sure did take a while to figure out what was wrong (finding the second .htaccess file). I learned a lot during the process after reading articles about cache, so this whole “headache” was actually worthwhile and will be critical to know in the future.
Here is what I did to fix MY problems:
– Delete plugin folder via ftp and all the other files as mentioned in above posts.
– Delete WT3 additions in the wp-config.php
– Find every .htaccess file in your site (I found two), from the wp folder to the site root, and remove the WT3 additions.
– Upload and refresh.
I hope this helps the next person that ends up exactly where I was.
