Hello,

You can restore your site from the backup before you have installed the theme. Then install the theme on Elementor.

If you can not go this way, there is another more complicated.

Install the WoodMart with Elemento on net WordPress installation (testing platform) and try to import all the content https://prnt.sc/xtrhbm

Then export-import the user table of the database into your new site and configure.

As soon as you configure, you will move the testing site to your living site and will not lose any content or user data.

Hope it would work.

Best Regards
