Reply To: Continue my previous custom change.

Hello,

Your site is in under construction mode and your admin access URL not working for me. I have tried the below four URLs to access your admin area but failed:
https://optikavision.gr/katrin/wp-admin
https://optikavision.gr/wp-admin/
https://optikavision.gr/katrin/?action=rp&key=1MTk4rd3gPJd68cZw03z&login=support_u2ccgv

Try to translate those previous and next strings from Loco Translate >> Plugins >> WooCommerce >> Search for your strings and translate them, and save the changes.
