[galaxy-dev] Unable to get data from UCSC

Hi, I am having lots of problems with the get data tools installed on our local galaxy server, I'll start with just one. With the UCSC Main one, I am unable to send data back to galaxy, when I click "Send query to Galaxy" nothing happens, the button is unresponsive. This is in contrast to when I try the same query from the main galaxy server, on the same browser and the content in correctly transferred back to galaxy. I have no idea how to start debugging this, there is nothing in paster.log Does anyone have any ideas? TIA, Anna
