Hello, Phillip
I haven't been able to replicate this yet (
https://trello.com/c/LdLlJDo9). Do you see any errors in your log near or after "GET /history/list HTTP/1.1"?
Shane Sturrock worked around this problem by updating his universe_wsgi.ini file (if I understand his procedure):
1. Make a backup of your universe_wsgi.ini file (for example, copy it to your home directory)
2. Rename the universe_wsgi.ini file in your galaxy installation something like 'universe_wsgi.ini.saved'
3. Rename the most recent universe_wsgi.ini.sample file (that came with the latest update) to universe_wsgi.ini.
4. Copy any custom settings for your server from your older universe_wsgi.ini.saved file to the newer universe_wsgi.ini file
5. Start Galaxy
That seemed to work for Shane. Ambrose re-installed and reconnected his database. Neither is a solution to the original cause, but you may want to try them while we investigate.
Thanks,
Carl
