From your addons list i'm not sure which one should cause this as I use a lot of these addons myself and never experienced any problems so far.
Backup your SavedVariables folder in total in order to get the data back if you experiment with addon settings etc.
So first update ALL your addons to the most current versions!
Check them ingame and compare them with
www.esoui.com to see if you really own the most current versions.
Attention: Some addons got fixed with another version called something like "fixed" or "summerset" etc. and the official addon is not working properly anymore. So check if there are replacements which work with these additions in the name (and uninstall the original ones before installigng the new ones).
Check if the chat, or a popup, is showing some error messages upon opening a coffer. If so post the message here please.
Try to disable the 1st half of your addons and check if it works then.
If not do the same with the 2nd half.
-> Use an addon profile helper to assist you, e.g.
http://www.esoui.com/downloads/info4...nProfiles.html
http://www.esoui.com/downloads/info1...nSelector.html
If this does not help it might be some addon from 1st half together with the 2nd half.
I'd start with the addons which change something in the item tooltips as the tooltip on your screenshot is empty and seems broken.
This process needs time but should be worth the effort (maybe other users suffer form that bug too).
