I have same issue… I have a valid licence for Flexform purchased through themeforest but support has run out and I have an issue with Swift Page builder not displaying correctly after a recent WP update, and wanted to view the fix at the following post:
Swift Page Builder do not work after WordPress-Update
It is saying I can’t view it as I don’t have a valid licence… but I do, I purchased the theme and would have thought I could still access/view the forum but not post (which is fine as I want to read the solution!)
Help!
