I have just upgraded to version 0.52 of WL
I went to alter a widget and found I cannot access any of my widgets. The list on the right hand side of the screen is there but no titles show and clicking on the down arrow does nothing.
Everyting was fine yesterday when I updated a couple of links.
The widgets still display and work OK on the website.
How can I revert to the previous version to find out if that is the problem?
