Most probably any old lib in a subfolder of your addons.
You should check ALL of your addons for subfolders like "lib" or "libs" and remove the libraries in there.
Download the libs once then from
www.esoui.com or using Minion addon manager, and install them to the live/AddOns folder directly.
This asures you got the newst version of the libs and Minion would be able to keep them updated easily for you.
All "libs" in subfolders are msot likely old, or can be replaced by these standalone (non-embedded) installations.
The %s stuff most likely happens because of any libChat (watch the non-capital l of the library name!) or libGarfield.
libCha, libChat1 libChat2 libChat3 and so on + libGarfield are not supported any longer. Delete them in total please and just use alternative libs. The updated addons tell you what dependencies are needed, e.g. LibchatMessage.
If any addon depends on the old libChatx libraries (the old ones): You need to find an replacement of the addon and deinstall that addon in total.
