I have downloaded the zip file for the LZ Interior Decor theme. However, when I upload it, all I get is the header. I cannot figure-out how to get the whole theme template to load, so I can then edit it with Elementor. I have tried everything! I went to “Templates” and “Add New” and then uploaded the Zip file. It appears under my templates and it is active. However, when I go to customize it, there is nothing but the header.
