Have been using WordPress plugin for over a year with no problems. Went to add a new PDF file today and when I click on Add New, a new page opens but I get a " Sorry something went wrong with the server please try again." Error. Cleared cache. Reinstalled plugin. Nothing has helped. Any ideas?
Open debugging console Ctrl+Shift+I in chrome.
Error: Incorrect contents fetched, please reload.
What am I looking for?
This is something new for me. I need access to your WP to check. author@3dflipbook.net
