I have some plugins that added tables to my wordpress database. I no longer use those plugins, and now want to clean up my database. Can I just delete the tables that were added by the plugins with no negative effects? Or is there some other way I should do it? Thanks
yes providing you have un-installed/de-activated the plugin first. also make a backup of the database just in case.
In the WordPress codex it lists all the WordPress tables from your fresh installation. As long as you don't delete the tables listed, or any tables used on an active plugin you should be alright. Link: http://codex.wordpress.org/Database_Description/2.3 (it says 2.3, but I'm pretty sure these are the same names for the tables in 2.5)
