 * Hi there,
   I have an issue to deactivate the NextGen plugin.There is this message
   coming and there is no way to move further:
 * _**Error thrown**
   Undefined constant ShortPixel\Controller\AdminNoticesController::
   MSG\_INTEGRATION\_NGGALLERY
 * Anybody have an idea what should I do?
   I contacted ShortPixel and they told me
   everything is fine with my settings on their plugin.Thank you very much for your
   help,
 * Kris

 * Hi [@decouverte](https://wordpress.org/support/users/decouverte/),
 * This appears to be a longstanding case that’s on ShortPixel side because they
   have an integration with NextGen and they may need to add an additional check
   if NextGen is active before they use that constant.
 * As a workaround, you can temporarily deactivate Shortpixel plugin first and only
   then deactivate NextGen.
