Do you use a database manager plugin? Usually optimizing your database will fix this. Good luck.
Which plugin? Obviously it has left something behind in your database. Naughty.
Thanks for the help guys. The plugin i Need to install again is called Simple WordPress Membership.
i do have one plugin called W3 Total Cache, which has been installed and activated ever since I took over the website.
I think that just comes with WordPress websites though
W3 Total Cache: Default settings are in use. The configuration file could not be read or doesn’t exist. Please save the settings to create the file.
It says that on the top of my plugins page. When I click it to save the settings, it fails.
Should I find a new database plugin maybe?
Hey @lrileypool, I don’t think W3 Total Cache is a database manager, but it could be part of the problem. Have you tried clearing the plugin’s cache? This setting / option should be found somewhere in the W3 Total Cache Settings screen. Sorry I can’t be more specific; I’ve never used this particular caching plugin.
Also, I use this database manager plugin .
It’s very reliable and it has both optimize and an empty / drop tables feature which may clean out whatever may have been left over from when you deleted the plugin earlier.
Good luck!
