Hi, Toufig,
what is not clear?
And nothing is happening with the web, it's a test, test server, that's why you can see the whole alternative address to hosting, SSL isn't turned on there, that's why the browser reports unsecured connections. Hosting is secure, I have hosting with the top Czech hosting company - Active24. I just didn't turn on SSL (https) to develop the site unnecessarily.
Hi, ssnobben:
Yes, I consulted the problem with JCE, they told me that there is probably, maybe, an error in loading the bootstrap in the template ...
Plus, it's not just a JCE script, but also ShadowboxPro. And only in the Ultimate template, not in Helix 3. (see my screencast above)
And it's weird that it only does that when I put a menu item in the Blog category property and turn on navigation there to the next (previous) page.
Heeeelp me, SOS, or I'm going crazy :-D :-D
