Hello,
i have just installed demo version of personal trainer3, there are no plugins yet and i am unable to switch to blocks editor since i can not save settings in bebuilder mode, also i am unable to save any edits to the page. (system status all green)
I already have 5+ installations with different themes from you but this is only one which is kinda broken.
page is: https://www.satinfit.sk/ but there are no changes from the demo since i can not make them.
also footer is not editable, it will open widgets but all footer widgets are empty, also in theme settings footer text is empty.
