I just upgraded my site to WP 3.7.1 The front end seems to be running fine. If I log into the backend things seem fine until I click on any link in i.e. the left menue ... then everything gets a grey overlay and the loading bar starts ... the problem with it is that nothing else ever happens. I.e. I cannot change anything, can't even deactivate plugins.
does anybody else get this?
thanx for any help
