How do I remove a binding

I am trying to remove a failed attempt to install a Davis weatherstation binding.
The installation procedure is to copy the appropriate jar file to the addons folder and create davis.cfg and davis.items files.
It didn’t work for me so I tried to remove it.
I’ve deleted the jar file and renamed the cfg and items files to txt files and rebooted. There are no Davis binding, things or items in PaperUI but I still get this message in the log.

 [ERROR] [core.karaf.internal.FeatureInstaller] - Failed installing 'openhab-binding-davis1'

What else do I have to delete or rename?

Have a look in addons.cfg.

If you don’t have this in your .cfg file then look here:

/var/lib/openhab2/config/org/openhab  or depending on what your running OH on /opt/openhab2/userdata/config/org/openhab

If you see the binding listed when using ls -al command (from the location above) then stop OH and manually delete it.

Thanks for the suggestions but I have already done both of these.
The addons.cfg is original, all line commented out and never been modified.
I’ve searched for and deleted all copies of the jar file.

Now look for addons.config
If you stop OH, you can delete that and it will be created anew, like a cache.

When manually installing bindings by adding jars to /add-ons/, I’ve found that sometimes you need to clear the OH cache to get rid of it.

Deleting addons.config got rid of the persistent error.
Thanks rossko.
