I have just updated to Pro 1.2.3 from 1.2.0 and the preview in Edit Page is no longer working. I can see the following JS errors.

cs-vendor.js?ver=2.1.3:19456 Uncaught TypeError: Cannot read property ‘indexOf’ of undefined

at DeferredActionQueues.flush (cs-vendor.js?ver=2.1.3:1207)
at Backburner.end (cs-vendor.js?ver=2.1.3:521)

What should I do?

Many thanks in advance.

Hi there,

Thanks for posting in.

It’s not due to update but because of a conflicting plugin. The cause of this is your Stickup Popup and WP Color box plugin, I went ahead and deactivated it.

Thanks!
