Hi, I’ve a problem with modules in footer-widgets position, after the joomla 3.6.4 update.
In the back-end side, when I try to open modules—> All modules published in footer-widgets positions, I can’t open it correctly: I find a blank page with top-left dopdown box that don’t work (see the attachment). I can’t go back with browser arrow, I can only rewrite the backend address and unlock the module. Then I can’t modify the content of the modules.
I see this also in a K2 module published in a right position.
Can someone help me?
