Hello, this is my home page:
Please look at the menu as reference, it's working properly on this page.
This is a blog post:
Issue is funny:
1. if you visit the blog post with a direct link, the menu WILL NOT work properly (wrong colors).
2. if you reach the blog post surfing from the home page, the menu will be ok.
3. in any case, if you click on a thumbnail, the gallery will not work properly the first time, opening just the image in the same tab. At this point, you can go back with the back button of the browser, and the thumbnails will now open the gallery correctly BUT THE MENU will look wrong. Menu will stay wrong even surfing on different pages from this point onward (unless you refresh while on home page)...
I have no idea how to debug this. Is the plugin or the theme? I can't code, I just have basic knowledge of HTML and CSS. Can you please help?
Theme is Stardust by Qode.
