Could you paste the content of the error message? :)

Thank you for filing this!

A user added template data to the citation template page Txantiloi:Erreferentzia, when there was already template data on the "dok" page at Txantiloi:Erreferentzia/dok.

This overwrote the working template data in the "dok" page, so consequently citoid wasn't fetching the correct configuration file and couldn't use the template at all.

I have fixed it now and it works. I did this by manually deleting the added template data (but not before accidentally removing all the template data very briefly - whoops :/ ) however it might be a good idea to check what I did, and maybe notify the user so they know to check for template data in the "dok" page in the future?

Here's where I removed the template data: https://eu.wikipedia.org/w/index.php?title=Txantiloi%3AErreferentzia&type=revision&diff=7776657&oldid=7776655

The user also added a .or to the template, I am not sure what this does but might be good to check it is okay as well?

Oopps! The user is me, so I get the notification. Thanks, I added the templatedata because I wasn't receiving it in the manual section. It may be a cache issue then, because now everything is working perfectly.

Thanks and take care!

Oh, haha, I should have noticed. :) Thanks! Yes, sometimes the cache takes a while to come through. Normally a null edit fixes this (where you edit the template page and save, but don't change anything.)
