Thanks for your quick response!
I think I figured it out and it might help others to know this bit of info. I went through the whole process of resetting my account with my hosting service and reinstalling WordPress. I reinstalled Evolve+ and all was back to normal.
HOWEVER! When I started to upload my plugins again I noticed the tabs and buttons once again disappeared. Through trial and error I found the plugin culprit: “Easy Responsive Tabs.” If you use this plugin it will wipe out the tabs and buttons for some reason so hopefully this can help anyone else with this issue.
