I just tested this theme which has many options. Depending on the demo chosen, the "WordPress Header Builder Plugin - Pearl" plugin is installed and some options, although present in Appearance / Customize, have no effect: You have to go through "Header Builder". To change this, you must deactivate the plugin. But in both cases, there are some options that I couldn't get to work properly, like showing a logo + the site title. When the plugin is activated, selecting a logo in "Header Builder" has no effect ... There is another point that bothers me: there are a lot of plugins and although I have selected a demo based on Elementor, the WPBackery plugin appears to be a recommended plugin ... But what is redibitory for me is that I chose the "Marsseille" demo and it only works on Chrome, the image transitions are very jerky with Firefox and Edge ...
