deleted all bagon files in addons
Downloaded n installed 7.3
Bags won't open unless I disable bagon

Hello, new here. I'm having the same issue, as is my roommate. The issue began first login after patch 7.3.
I have also uninstalled/reinstalled bagnon, verified all settings in wow, etc. I will attach the swatter info.

bagnon_failure_patch7.3.txt

I have this issue almost every time a new patch comes out :( I had to disable until it gets updated again.

Did you try downloading the following zipped up fix for this from the Project Issue #585:

Bagnon_73_Ready.zip

Just downloaded the zip and it works!! Thank you!!

Downloaded and unzipped, works perfect! Thank you very much! :)
