Themeshopy
Many thanks. It does seem to have resolved the issue, so I don’t have to keep jumping between Themes.
@madebyproxy – Many thanks for the input. I have checked out the Advanced IT Company Theme, but can not find the option to disable the loading screen, so it looks like the best way forward will be to follow the links you have sent and look to set up my own theme.
As a short term work around, I have found that if I change theme, to say the basic IT Company Theme, I can edit using elementor, and then revert back to the Advanced IT Company Theme when I have finished the editing. It is a real pain, particularly when people might be viewing the website, as the layout changes dramatically when doing this. However, it buys me some time to learn how to make my own theme.
Once again, thanks for the input.
