Since yesterday, I have found that several buttons on the Dashboard are not working. When I am editing a post, the Add Category button doesn't work and I cannot create new tags (I can type them in the tag field, but they are not added to the post). When I click the "Choose most used tags" link, nothing happens. Well, the URL changes, going from ending with "action=edit" to "action=edit#category-add".
I've logged out, re-started by browser, re-booted my computer. Other sites are working fine...and much of the Dashboard functionality is working, but I cannot add tags to my posts at all at this point.
The blog I need help with is cookinggaps.wordpress.com.
