Hi, today i did a purge of sef url and all my k2 SEF url changed sef from: www.xxxx.net/category1/category2/alias to www.xxxx.net/alias
Example:
https://www.xxxx.net/sport-popolare/elenco-corsi-palestra/pilates
Now is https://www.xxxx.net/pilates
So now all the the link previously indexed by google give error 404.
How can enable again category in K2 sef url?
