I tried installing the marketer template from the site library and it got installed but after that, I overwrite it with another template with elementor page builder. Now after removing that template, It started to show some error message in the header section of the WP dashboard and site header. When I deleted elementor plugin, It got corrected but the first template is still there, which I am not able to delete. Kindly let me know how to delete the template, since I did not let me customize my site.
