Additional context
I believe the issue centers around error "3/4" as I have a second account using the same WoW install, but I can see bag contents on that account just fine. the 3rd error is the only one that appears on the problematic account.

Same - bags won't "open" for view

This (and many other) bag addons got bit by a change to the ItemButtonTemplate made in 8.1.5

Getting one of these errors myself since patch but bags open just fine. However when trying to open my bank I get the second error and it looks much the same as OP's image there, no slots only the top bar and bottom bar showing money and the bagnon buttons. Clicking to open the bag slots button and clicking a bag slot to disable it seems to fix the problem and would appear to be a work-around for the time being. Edit No not working fine, got some random items from higher up my bank appearing in my reagent portion when I click on certain item stacks there (reagent will blink and icon of the other item appears for a moment), trying to interact with these just interacts with the item whose icon is hidden beneath the reagent item icon.

I still get the errors, but I can see my bag content again, after I turned off "display blizzard frames for hidden bags" in bagnon settings

Same here - awesome - ty for the temp fix until they patch it - I was going crazy trying to relearn default bag ui after 10 years -

EDIT: Is your bank working though? Just realized mine isn't

My bank bags + fame are working. But my guild bags wont open as same, in Greenginko's Screenshot above. Wake up American and fix again please!

See #885 <= Click here -- see if this works for you

Latest patch sliced into release seems to have cleared up all the lua errors being thrown.

Same problem, but the fix provided by @Sommerulv doesn't work for me

There is a setting in Bagnon "display bliz frames for hidden bags" uncheck that
