problem with links

Hello,

on the website, I have webshop (woocommerce). I tried to translate it via Loco plugin, but something went wrong. Translation on Croatian language did not show, but that is not only problem – after trying to translate, something went wrong with links (categories in webshop – when I click on some category , there is message “Nothing Found”..now I deleted Loco plugin but links are still not active (pleaese see on link below)

Maybe, link problem is not connected to loco plugin, but I don’t know what to do now.
I would be very greatful if you could help me with this problem and maybe if you can help me to translate woocommerce plugin on Croatian language.

In advance, thank you very much…
Best Regards,
Marijana
