Hello! I am having some trouble working with Upfront's visual editor on one of my websites. I am attempting to move a tab element from one section to another, but when I click on the element to drag it, the element disappears and the rest of the site grays out. I have to refresh the webpage in order to edit other elements. The issue is occurring in Google Chrome (v47.0.2526.80 m; Windows 7). I don't currently have access to FireFox, and upfront editor does not work at all in IE (v9.0).
There are no updates available, I haven't installed any new plugins, and all other themes have been removed from the website. I am able to move other elements without issue. Screenshots of the issue are attached.
I have granted you access to the site through my Support panel of the WPMU plugin.
Do you have any advice for how to resolve this situation?
