Have been using your Page Builder to construct pages. It has been very slow, but still worked for me... until yesterday. Now when I try to save changes it gives me the message "This Site says... error" and my changes are not saved. This began right after I tried adding a "Creative Services" element to a page I had successfully created days ago using Page Builder. Now nothing can be saved, even changes to elements in the page builder that had been working fine all week. I even tried creating a brand new template and starting from scratch. Same error message. Ugh!
P.S. Again, the search feature on your support forum is broken. Without a working search tool, it's impossible to find anything in your forums without spending an hour browsing from page to page and reading everything. So if the answer to this problem has already been address somewhere, I apologize.
