Broken theme’s customizer since v2.1.9

hi,

Thank you for your excellent plugin, but since the latest uptade I cannot have access to my theme’s customizer. I always have a blank page and a piece of url like so: customize.php?return=%2Fwp-admin%2

I tried to uninstall the plugin and then it worked, so it is related to the plugin… It’s too bad, I would like to use it ??

Thank you for your help.
