And when it IS activated, there’s a persistent error at the top of your admin panel? * If that’s the case, then deactivate and delete our whole plugin folder entirely from your /plugins folder (i prefer FTP), and then try to install a new version. * If the problem persists, then there must be some conflict with some other plugin on your site, and a methodical disabling / enabling of the others would be necessary to track it down. * If you can do the legwork to determine which plugin we may be in conflict with, we’ll take a look and see if it should be fixed on our end…. * Typically, I think it’s the responsibility of the less popular of two conflicting plugins to ensure compatibility – for example, if we conflict with a popular plugin with half a million downloads, and we have only 50,000 users, then it’s on us. * Please post back here further, and I’ll also ask Heather (dzynit) to chime in in case she has any ideas… * Plugin Author [Dzynit](https://wordpress.org/support/users/dzynit/) * (@dzynit) * [13 years, 1 month ago](https://wordpress.org/support/topic/plugin-seo-tools-error/#post-3109284) * The headers already sent message is most commonly a plugin conflict or when the plugin files corrupted during installation. I occasionally have a problem where the plugin files didn’t fully unpack and install correctly because the server had suddenly gone down at the time of installation. * Scott’s suggestions are best to try first. Deactivate seo tools, fully delete it and try installing it fresh first to see if there was a corruption during installation. If the error persists, as tedious as it may be – turning off all your active plugins, activate seo tools first, and one by one reactivate all your others, each time testing a new plugin search to see when you get that second error. * Since it really wouldn’t take much time, if you want to send me a zip of only your active plugins, I can put them on a test site simply to confirm it being the plugins and not a possible server configuration. I don’t currently have available time to test for which plugin is the conflict, but can at least help to confirm that it definitely is a conflict. You can send the zip to heather(at)searchcommander. com if you want me to do that. * Plugin Author [Scott Hendison](https://wordpress.org/support/users/cyber49/) * (@cyber49) * [12 years, 9 months ago](https://wordpress.org/support/topic/plugin-seo-tools-error/#post-3109301) * No zip was ever sent, and we can only do so much without help from the site owner, so I’m marking this as resolved.
