Can't Open Tweet This Dialog Box

Replies: 10

Clicking on the blue bird icon in the WordPress post editor appears to do nothing. Checked my javascript console and found this:

Uncaught Error: cannot call methods on dialog prior to initialization; attempted to call method 'open'
    m.extend.error @ jquery.js?ver=1.11.2:2
    (anonymous function) @ widget.min.js?ver=1.11.4:11
    m.extend.each @ jquery.js?ver=1.11.2:2
    m.fn.m.each @ jquery.js?ver=1.11.2:2

If I put in the the [tweetthis][/tweetthis] delimiters in manually, everything works fine. But the users I’m developing this for will definitely need the dialog box functionality.

Any ideas on how to remedy this? Thanks for the plugin.
