Have just done a fresh install of WordPress and added the Customizr theme along with the Toolset plugins, unfortunately activating Layouts seems to break the customisation settings for the theme - the drop down menus allowing you to set font group, colours etc. no longer work.
Neither Firefox or IE seem to be showing any scripting errors.
Attached is a screen grab showing one of the effected menus working when Layouts is disabled,
I set up a test site and can confirm the issue. The select options for the different fonts are all present in the markup, but it is not possible to open the dropdown.
I have escalated this to our compatibility team to address the problem and produce a fix, and I'll update you as soon as I have anything to report.
All working, thanks for sorting it - probably not a huge bug in the grand scheme of things but saves me having to deactivate the plugin just to try new fonts out lol.
This ticket is now closed. If you're a WPML client and need related help, please open a new support ticket.
