Nextgen Gallery errors

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:

Notice: Undefined index: mobile-menu/freemius in C:\wamp64\www\wordpress\wp-content\plugins\nextgen-gallery\freemius\start.php on line 184

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.
