I've been having an issue to get the shortcodes dropdown button to display in my editor.
Problem persists even though I have done following:
1) Tried in Firefox
2) Tried in Chrome
3) Cleared browser cache
4) Disabled all plugins except for Ultimate TinyMCE
5) Resetting plugin
Also, if I enable Firebug on editor page - interestingly I get the following error:
"invalid regular expression flag h
Any ideas anyone?
