I think we have uncovered a bug related to the HTML text widget on community space customization in Clearspace X 1.6. It has happened a couple of times when I have edited the HTML text to add text and images that after I publish the layout, only the next widget and those above it on the left hand side are visible. When I go back to try and re-configure the space, the widgets won't drag.
We had support working on the issue for a while but weren't getting very far. I was able to "restore" the layout and functionality today by choosing "Copy from another community," but this doesn't fix the issue of the HTML widget causing the problem in the first place.
Are y'all aware of this or is this unique to our installation somehow? Anybody else experienced this?
Does the HTML you're adding include the <html> and <body> tags? The HTML Text widget doesn't currently support those tags (those tags already exist in the larger page, of course). See if this related thread sounds familiar: Error when using html widget
