Hi there, strange things happening.
I’m using X Pro 4.3.3 in Worpdress 5.7.2 environment and, suddenly, while working on column gaps, the Layout (single post) editor got stuck in a loop.
Oddily enough, I CAN edit Headers, Footers, Contents, build new layouts but I CAN’T work on the Single Post custom Layout I already built.
Working on Mac OS Big Sur with Brave browser v 1.26.77 installed.
Had a load of previous posts regarding similar subject but no clue.
Browser cache crystal clear. Also try to login with different browsers (Safari 14.1.1, Chrome 91.0.4472.114).
Any thoughts?
