Hello,
Thanks for the topic.
Please make sure that you also updated all plugins https://www.8theme.com/download-plugins/ (To update free plugins just click on update link from your Dashboard (Plugins > Installed Plugins). To update premium plugins, connect to your server using FTP. Copy extracted plugins folders into wp-content/plugins/ ).
Delete “woocommerce” folder, which is located in wp-content/themes/legenda/ and upload this folder from latest theme archive, to avoid problems with old files.
If your problems won’t be solved, please provide me temporary wp-admin and FTP access.
Regards
