Hi,
I think I have the same problem as some other users of SP Page Builder pro on Joomla 4.0.3.
Episode 1 :
When I click SAVE from front-end editor, I have a message saying page is saved but when I'm back to my page in the backend, nothing has been saved and all my new work is lost. only backend editor is ok (but not convenient at all).
SO... I tried this on a brand new J4.0.3 site with nothing else except akeeba backup pro. Everything went fine until I decide to link a page to a joomla menu item.
Episode 2 :
I've just found that if I click on SAVE from frontend editor and then look at the backend editor tab on my browser(chrome or firefox), then no modification had been taken into account EXCEPT IF I click on the page refresh circle arrow of my browser for that backend tab !!!.
Like a miracle, instantly all modifications are transfered on backend editor so that everything can be saved. TO sum-up, the save button from frontend editor should actualize the backend editor browser tab.
Questions aside :
Is it normal that if from the backend editor you click on the "frontend editor" button, a new tab on the browser appears for that frontend ?
I saw also the "close" button from frontend editor only closing the left blue editor pane but not closing the entire frontend tab. Is it a normal behavior ?
If I remember the first time I tried this "close" button, the tab dissapeared and all new editions appeared back in the backend editor ready to be saved or maybe allready saved.
Hope It helps or you could help me. I'm using last chrome and no helix3 or other framework had been used on the new "test" nude website. I directly installed the SP PB Pro.
Best regards,
Ed
