 * Hello,
 * A very odd problem has just occured on a local test site I am working on.
 * I was trying out Responsive Menu plugin and WP Mobile Menu plugin but did not
   like them so I deactivated and deleted them, after that I got a few errors all
   realted to Nextgen Gallery.
 * I don’t understand how uninstalling a plugin can cause erros like this. I never
   had any mobile menu plugin installed 30 minutes ago and everything was fine.
 * Here is the errors:

 * Errors seemt o be related to freemius, after a quick google search I can see 
   than WP Mobile Menu uses Freemius(still not sure exactly what freemius is yet.)/
   Freemius, whatever it is sounds like bad news if it can cause these errors, should
   consider using something else in the future.
 * Thankfully this is just a test site, so I can re-install next gen and see if 
   the errors dissapear.

 * Hi [@gamerwithadegree](https://wordpress.org/support/users/gamerwithadegree/),
 * Many plugins ( including NextGen ) are using Freemius that helps to track some
   and create some statistic data ref the amount of plugin’s installations for the
   business management purposes.
 * The same time, the Freemius submodule seems to cause a problem in case that you
   are opting to activate it from 2 or more plugins that are using it but luckily,
   you can “Opt Out” from NextGen’s Freemius by accessing “Dashboard -> Plugins”
   and press on the “Opt Out” button that’s next to the “Deactivate” button.
 * This should solve the problem
