I seem to be having the same problem as others here. I created a user timeline widget, then in wordpress created a new sidebar, added a html block and pasted in the code. But all that comes up is a single line of text saying tweets by the_craftcorner. Here is the link http://thecraftcorner.ie/home/classes/booking-completed/
I read what you said about the url. Here are the URL’s I entered. thecraftcorner.ie, www.thecraftcorner.
I have checked it out in firefox and google chrome. Any advice? Thanks Vanessa
