Dear all, I am very new into Galaxy. I was doing analysis on the ucsc based service and i had problems making a workflow from my history. I did install galaxy on my computer (Mac OS 10.5.5, running python 2.5.1) thinking it may be easier to track the problem. I get this error message on the web "Server ErrorAn error occurred. See the error logs for more information. (Turn debug on to display exception reports here)" and the one at the bottom with the local installation. I get the same error if I try to make the workflow from scratch. I hope you can help me.
