Server won't start after removing mods

Well, the title says it. The problem is with the baubles mod, which appears to leave items around. Here's what the console says about it:

Am I supposed to uninstall them in some other way besides removing the .jar file? Should I go back to the 1.9.4 version and start the server with the mod uninstalled before going to 1.10?

Bumping with some attemps I did.

 

I tried running the server with 1.9.4 and removing the mods from that version. Also tried with other mods, such as Wonderful Wands. Still the same error, missing items and server won't start. I tried cleaning my player's inventories from the removed mod's items, but still won't work.

 

I never thought it would be so hard to uninstall a mod, haha.
