oik plugins are WordPress plugins that are supported from oik plugin servers, not WordPress.org. You can use the oik options > Plugins page to manage the versions of these plugins. Here we see a list of the registered oik plugins and the servers from which they are supported. For each plugin listed there are 3 actions: Delete – Removes the entry from the plugin server settings page. Note: This does not delete the plugin. You might want to use this for a plugin that is served from WordPress.org. Edit – Edit the entry – to set the server URL or the apikey Check – To check if the plugin needs updating. Use the Add plugin button to add a new plugin as an oik plugin. This is useful when you want to update to a development version of a plugin.
