I am using a theme call Construct by Squidix. In the theme options menu the drop down menus are not appearing. I contacted the Squidix developers and they told me it was a problem with the Option Tree plugin that appeared after the latest WordPress version came out a short time ago (3.5.0. or 3.5.1.). Are you guys working on a solution for this? Thank you for your time and efforts to supply us with this great plugin.
