 * sorry for the issue, we were to fast releasing. It is fixed in 5.0.3. Unfortunately
   you will manually have to disable / delete the old plugin files either from your
   database or by deleting / renaming the folder.

 * Here is a short tutorial about it, you will have to do it for the wp-content/
   plugins/eedee-gutenslider folder.
 * If you need more help please ask.
