I am having my students use the RNAseq tutorial data from jeremy's post here:
and after signing up for Galaxy the first thing they do is import the history from jeremy's tutorial into their own but many get "This site says... History could not be imported. Please contact a Galaxy administrator". They are using usegalaxy (Main). This has happened on Chrome, Safari and Firefox, and on Windows and Apple machines. I have had them clear their cookies and restart their browsers which fixes the problem only for some. One student had success after turning off ad blocker, but I run that without interference on my machine.
Any help would be appreciated!
