Hi, I have updated both SPPB to 3.7.14 and Helix Ultimate to 2.0.4 recently, so I don't know which of both is causing the problem, but my guess would be Helix.
Since the updates, only one language menu is displayed, the one from the browser settings (German browser displays only German menu, English browser only English menu). All other language menus are not displayed. Moreover, the offcanvas menus does not work anymore in any language (page just turns greyish, no menu displayed).
I have double-checked all language plugin and module settings and the language-specific Helix styles, but found no solution, everything looks correct.
The site was built on the default Helix template, with some additional pages in "Corporate" layout. Joomla version is 3.10.1.
Any help would be much appreciated!
