I updated wordpress and Gforms today to the latest versions (3.3 and 1.6.2) and cant insert forms into posts or pages. I have created the form, and then try to use the insert button above the tinymce editor. the window opens and I select the form but the insert button does nothing. No error, window stays open.
I am using Chrome, but have also got the same results using ff, also I am using tinymce advanced plugin, and I haven't tried debugging by disabling anything.
If anyone knows what could be going on it's great. I typed in my own shortcode as a wrokaround for now.
