Help! Up until yesterday, my Newsletter plugin worked great. Now I can pick the template I want and choose which posts to view, but then when I click “Proceed to Edit” I get an all black screen with a thin pink line along the left side. I can’t make any edits. I can click next and see the functionality seems to be working on that page. I can even see a preview. This is blocking me from sending newsletters to my subscribers because I can’t make any edits. Help!!
Note, I’m not a premium customer, but I never was and used the free version with no issues.
