I have been having UI error issues on and off for months.

At one point I removed all my addons and started again from scratch, loading in just addons I actually use incase there was a conflict somewhere.

MM still regularily throws errors, most notably these errors reference "async" a lot. In this time the author has added several new libs but the issue stays!!

Tbh I have pretty much given up, I just have MM active on one character most of the time and I now use ATT and TTC for pricing guidance.

The only reason I even keep MM is it remembers my listing prices and that saves me time.

However I don't have any issues with it showing me prices, have you double checked your settings within the addon, it is possible some have changed on their own after updates?

If your settings are all correct do you run libhistoire regularily? If you don't that can cause pricing data issues. Sometimes if I'm only on for a short while the data doesn't update for the last day's sales.

Also if you have the problem, when trying to update sales, of the ever spinning wheel trying to retrieve data, well I solve that by disabling MM and updating libhistoire before turning MM back on, turning it off will throw an error too though!

For the person who started the thread: it's not useful to say "MM-related UI error popup" without saying what the error actually says.

For people talking about dependencies: if dependencies are missing, then they won't get UI errors because the addon won't even load.

Ok, here it is:

Thank you! I think it worked!

I'm having this issue as well.
Replaced all Lib files with fresh, etc. all that stuff.
I had noticed with my Master Merchant that since the last update I used to be able to see a sale value for items based on a 10 day window, and I could also check for a 3 day window. Haven't been able to check for the 3 day window at all though the settings still say I should be able to.
No missing libraries.
Quite frustrating.

Today's session gave me no UI errors, so maybe it fixed itself. Takes forever to fill in missing history data though.
