I am having the same problem. Just downloaded Quest a few days ago so it’s 1.2.7. The page builder was working fine until this morning, and the save.php fix actually broke my site so that I couldn’t edit the page in question at all. Every time I clicked “save” I got a white screen afterward…and nothing was saved, obviously.
Had to re-download the theme and use the old save.php, but it didn’t fix the problem.
Can you post an older, more stable version of the theme for download? Or undo the recent update? It was working fine yesterday 🙁
