Hello I added a custom build to Galaxy, then deleted it and added a new build with the same name. Now whenever I try to acces my custom builds I am getting a server error. Can you point me towards any faults? Do I need to manually remove the custom builds from the database and if so where can I find them? Thanks Shaun Webb Error - <type 'exceptions.KeyError'>: u'ensembl_Current' URL: http://bifx-core.bio.ed.ac.uk:8080/galaxy/display_application/4100358d24a8f6...
