Hello,
I would recommend you activate default theme, for example, Storefront theme, on your site, then update all plugins http://prntscr.com/gt251j and update the theme via FTP (you need delete “woocommerce” folder, which is located in wp-content/themes/idstore/ (via ftp) there is only one such folder, you do not need to delete plugins before theme update), after that, you may activate idstore theme.
Don’t forget to create backup of your files and database before starting update process!
Regards
