Hi to everyone, 
This is just a post about how to understand, handle and fix tag errors and tag issues in MateCat, the CAT tool we use on Kató. After going over some translations, I realized that I’d been many times involved in tag issues of different sorts and I think this link could be especially useful for new users! I’ve seen other similar posts on the platform but as soon as I came across this post on matecat’s official website, I immediately though of sharing it here. It’s clear, well organized and conveniently concise.
Hope you find it useful!
