Upgrading a plugin is pretty straightforward, just.. Deactivate the plugin (Click the green circle in Admin -> Plugin Management) Upload the new plugin version, overwriting the old one Reactivate the plugin by clicking the circle again. If you encounter any problems, try going to Admin -> Maintenance and clearing the 4 caches. Follow that up with a hard refresh (CTRL+F5) and you should be back on track. Failing that, please read Troubleshooting Unexpected Errors. Note: It's not necessary to uninstall a plugin to upgrade it, but it's generally safe to do so. If you have any problems, leave a note for the plugin developer on the plugin's page in the Plugin Downloads forum.
