I'm writing a plugin, but I seem to have done something wrong that I cannot figure out. When I try to install my plugin, the install works fine, but when I click the "Activate" link, I get a message that says: "Your WordPress database is already up-to-date!". However, the plugin does not become active.
I have tried removing the plugin and reinstalling. I've tried bumping the version number in my plugin-name.php file and "Upgrading" but every thing I try I still get the database is up-to-date message and an inactive plugin.
