I cannot follow you sorry
If PotionMaker menu is opened you can see GridList? This is not normal and is a bug then.
And keybinds are not the problems then.
I guess it's any other addon you got enabled that interferes!
e.g. Complete delete the InventoryGridView folder in live/AddOns!
Try the following:
Disable ALL addons and ALL libraries!
Install and enable ONLY "Grid List" and the needed dependencies.
Reload the Ui and open the inventory.
Does GridList show the icon at the inventory to toggle the grid list (toggle between normal inventory and GridList)?
If not you have either not installed the most recent version of GridList and the needed dependencies and need to check you got all the newest versions, or you got any other addon enabled ->
Logout, close the game.
Move ALL addons and libraries out of live/AddOns.
Only copy the needed libraries and GridLst folder back in and assure you got the newest versions installed.
Maybe manually download and update them again and check the contents of the folders.
If it works then it's another addon which interferes. As you said Potion Maker maybe an issue do the same for it:
Update all properly and only move the libraries needed and PotionMaker addon folder to live/AddOns, together with GridLst.
ry if enabling both works now.
If yes: It was another addon which made it fail to run! You need to find out which of your addons it was by manually checking 1 after another then.
If no:
Please describe again what is not working with the keybind or what you found out. At best: Use screenshots OR a video! As we cannot seem to properly understand what you expalin by text, sorry
