Elementor – theme issue

Hello, Site: tksealing.com I have deleted and re-installed the Solid Construction page. Still having issues with Elementor and the theme. I also deleted several plug-ins but still cannot figure out why this isn't working properly. In "Page" I can edit the homepage ONLY if I choose to edit this way: If I click "edit", the page goes blank. If I click "edit with elementor", I can edit. However, when I choose "return to dashboard" the page goes blank. I cannot edit the "blog" page: When I choose "edit with elementor" I get the message "The preview could not be loaded" and "We're sorry. Something went wrong..." In "Post" Since there is no option to "edit with elementor" I cannot edit any of the posts ... the screen Help! Thank you, Byron
