I can not edit anything after the wordpress 4.5 update
Try updating BB to the new v1.7.7 and see if that fixes it. Give that a shot and let us know how it goes. Thanks!
The update was already done before contacting you so yes I still have the same problem.
Also I checked with the theme support and they have not had any issues since the update with this theme. I also have the same theme & same BB plugin across several sites and I have not updated to Wordpress 4.5 on any of those sites and the plugin works fine on all of those sites.
Also got the new 1.7.8 Just now and updated it and still not working.
Can you share temp admin access to the site in question so we can check?
Do we have permission to disable plugins and switch themes?
