even after deactivating Autoptimize and W3 Total Cache, Elementor still has the same bug, i think the last couple of updates are the fault. well thats a mths work wasted i am going to switch to one of the more established drag & drop page builder as, should have done this in the beginning but got sucked in by the massive youtube hype about elementor.

i have this same problem, every-time i make anew page with Elementor, next day or sometimes within the hour, the page loses all its formating, and the text and images are all in a single column.

it has been doing it with the last 2 updates, version 1.5.1 and 1.5.2

i see you mention cache plug-ins as a possible cause. i have Autoptimize and W3 Total Cache installed, i will deactivate them an try one more time with Elementor.

i have had a similar problem were this am getting new admin accounts created every 30 minutes or so for 2 days now. they are using the below to create the admin accounts. and it seems to have started since i updated to the current wordpress version 4.7.4 but this could just be a coincidence.
