Thank you for providing the error logs. Are you using MySQL DB or another type of DB?

Ubuntu 14
Apache 2.4
MySQL 5.5
PHP 5.6

Also, I just checked and this plugin creates 7 DB tables. Woah…

Please add an uninstall hook for these DB tables when this plugin is deleted.

Thanks

Fair enough statement. I will see about getting an update out for the “Headers already sent” error. I am assuming you are installing fresh?

I will update this thread here when the push has been made.

I have pushed an update. I will be working on adding an uninstall option to the plugin as well here shortly. Thank you for letting me know about the issues.

Cool. I just installed the update with debug on and the plugin activated fine. So I’ll mark this as solved.

FYI, in your settings pages, it looks like a tabs() dependency is missing in your admin.js file. I haven’t inspected any of your source, but I just see this in JS Notifier and Console.
