Recently I migrated my site to a live server and ever since then I'm unable to edit the headers and footers of the site – created by the plugin « Header and Footer blocks » by Brainstorm force – but only when these headers and footers have been published live, i.e. if they are only in draft mode I can edit them just fine.
When I try to edit a header or a footer I get the never-ending gray Elementor loading screen. When I open the browser dev console I'm getting that exception: https://paste.ofcode.org/KpEU5azv8vFrFKx7AxAfem
I've already tried disabling all plugins and it seems to have done anything.
Btw it's important that I can edit the normal pages just fine whether draft or live
