Imagine my surprise when I logged on yesterday & found that the 4 selection buttons are replaced with tabs. That by itself is OK, but the Activities tab gives the error "The page you were trying to visit has been specified as off limits by the site Webmaster" when clicked on. I'm the webmaster & I have not specified it off-limits. However, even if I did, I should have access to it at all times being the webmaster. It did work before the change. Please fix.
Thank you for reporting this, we will try to fix this problem as soon as possible. The reason that this happens is because you have the news section turned off in your site.Until we fix this, in order to get into the activities tab add the news section back into your site.
You can do this by clicking on the 'settings' tab and then the 'Content' link. Check 'News' and click the 'Save' button (at the bottom right).
Once we have this fixed you can remove the news section again.
The bug needs a fix, but with suggestions made by another webmaster, Ellen (Thompson) Francis, I figured out a workaround. Login as webmaster. Go to Settings, Content. Select all the options in Content (& save it). Then go back & deselect the options you don't want (& save it). Activities will now be accessible to the webmaster & members.
Apparently, the GUI has some troubles dealing with the recent upgrade & can't seamlessly transfer the settings from each site's individual Activities. Resetting the Content seems to straighten it out.
