I've seen Super Cache recommended in so many places,but it should come with a warning!
I am so used to other plugins with straightforward installs and uninstalls, it never occurred to me uninstalling a plugin would be so hard - especially as I hadn't even completed the installation.
I thought I'd followed the uninstall instructions but my site broke. Then I tried the "if all else fails and your site is broken" instructions. My site is still broken.
If I'd known the plugin required modification of .htaccess etc,and that the uninstall wouldn't be straightforward, I wouldn't have used it. I know I'm not technically proficient so I would have steered clear. :(
Now i have no clue how to get my site back up and running. The only page that works is the home page.
