Hi Offi,
The manu issue occurrs whenever on any menu items besides the Hyundai and Isuzu styles on the template. If you navigate to, for example, the Volkswagen lineup, or the preowned lineup, the menu is a blur. So the off canvas menu is not working correctly on some of the styles, while working correctly on others.
My apologies if I did not explained on detail that since we run different brands, we do have a distinct template style for each. We run a Core style for the overall site, with specific templates for Hyundai, Isuzu and Volkswagen cehicles, an additional style for Commercial vehicles, and yet an additional style for Preowned units. All of them were moved to Helix Ultimate recently, based on advice, and specially pending migration to Joomla 4. The off-canvas is working on the Core and Hyundai styles, while it doesn't on the remaining styles.
The blur on load can be seen on my end, and it was tested on both Mac and PC desktops running two different browsers (Chrome on Mac, Firefox on PC). Tne flicker as can be seen fom the video is present on both cases.
Also, there was also an issue in regards of fonts. I have selected distinct Google Fonts for each brand. Yet on the page many of the brands show in standard non-serif. THIS WAS SOLVED BY UNCHECKING THE COMPRESS GOOGLE FONTS SETTING IN JCH OPTIMIZER PRO.
Please advice.
Rgds,
Rodney
