Bank will not open at all, even though bags are opening on character.

It doesnt error or present anything just doesnt open or happen.

Disabling the addon fixes the issue.

Exit WoW
Got to: [Drive letter]:\World of Warcraft_retail_\WTF\Account[YOUR ACCOUNT NAME]\SavedVariables
Delete all Bagnon entries
Relaunch game and enable all Bagnon addons, and it will work like a charm

Having the same issue. Tried the proposed fix, couldn't locate any Bagnon entries under the proposed file path (actually had no entries at all for saved variables). Ended up deleting and reinstalling all addons, including Bagnon. At first that seemed to fix the no bags showing at the bank, but after a few minutes I noticed I no longer had a bag slots bar. And after a few more minutes bags at the bank once again stopped showing and I am back to square one with the problem.

BugSack addon is telling me there's definitely an issue with Bagnon that keeps happening (not the ONLY issue, but the only one related to Bagnon) - the error text I receive prior to the temporary fix of deleting/reinstalling all add-ons is

This works but I couldn't see my bank bags bar. Then when I /reloadUI, the bank stops showing up again. Same issue with guild bank. Just doesn't open window.

This works but I couldn't see my bank bags bar.

Bagnon settings -> Frame settings -> Inventory -> Databroker Plugins

Enabled this and the icon that lets you open the bank showed up.

didn't realy help me finding them to delete, but anyone unable to find thier wtf saved variables to delete, you likely also have/had multiple accounts, and they are saved under the individual accounts wtf folders.

I am having the same problem, and there are no Bagnon related entries in SavedVariables.

Also, when I enable "separate reagents tab," only the reagents tab shows -- no bag bar visible to view the actual bank.

Deleting Saved Variables in the WTF/Account folder worked for me

This worked perfectly!! Thank you

The proposed fix of removing the Bagnon files under SavedVariables does not work. It worked on my main but when I logged with an alt I still had the issue.

Also, these files are under the main Account folder and not each individual character, at least for me.

The variable deletion ONLY works until the VERY FIRST change you make. AS SOON as you change even one setting and RE-launch the game - the issue is back and bank is not working at all...

The only workaround is the commenting trick for lines 188,189 in the bag.lua file..

I hope an actual addon-embedded fix is patched soon and published as an officially released version.
