I need help. I can't access widgets on the backend...

[vladskiy]

I upgraded from v1.4.6 to v1.5.0. Everything is working well, however, I cannot access my widgets under extend. When I click on widgets, the loading line goes about 75 percent and theit the loading icon keeps spinning without going anywhere !
