Hi there,
I have had the same problem, but I have found that you do not need to disable the whole plugin. If you go to the SG Security settings and uncheck ‘Hide WordPress Version’ then you will be able to edit with Elementor Pro.
I have been unchecking it whilst I edit it and then rechecking it afterwards.
@sg Security, if there is a fix for this please let me know.
Hope this helps.
