I just noticed that one of my blogs savvyexaminer.com is which is using both Graphene and Graphene Neo is not able to create categories anymore. What’s more, when you select the Categories page none of my categories are listed. Viewing all my posts does show that there are categories assigned to each post but it’s no longer possible to create a new category, or to assign a category to any post new or old.
I have reinstalled WordPress. I hope I don’t have to reinstall Graphene and Neo. WordPress support has not been helpful. I’d appreciate any suggestions.
