Hi

We still have a few websites who were developed years ago using the Toolset Layouts plugin.

After updating to the newest WP 6.6.1 the navigation menus seem to break. Top level menu items are still being shown, but dropdown menus disappear completely. Even the HTML for the dropdown is removed from the page.

After downgrading to WordPress 6.5.5 the dropdown menus work again.

No errors appear in the console, and the error logs on the hosting don't shown any problems either.

Do you still provide support for these bugs?

This occurs on all our websites still using Toolset Layouts

Thanks in advance,
Niek
