Cannot Add New Slide

Thanks for the great plugin. I’ve recently run in to an issue with the latest update. I’m using version 3.2.6 of the plugin and cannot seem to add a new slide to an existing slider. I get the following error:

Uncaught TypeError: Cannot read property ‘limitExceeded’ of undefined
