i have done everything from above said article but the problem remain just for BLOCKS section. overall its working good.
secondally you told i am using elementor demo version what does it means i have installed elementor from your plugin installer. and kindly share image via any other way bcaz i cant see your shared image
Provide screenshot of the Permalinks settings, please.
Rose meant that you use the Elementor (default version) not the WPBakery plugin that is premium plugin.
But Elementor is handier as for me, so good choice.
