I too have now got a screen full of errors after upgrading.
" Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'woocommerce_reset_loop' not found or invalid function name in /var/www/vhosts/xxxxxxxxx/httpdocs/xxxxxxxxxx/wp-includes/plugin.php on line 507
Warning: Cannot modify header information - headers already sent by (output started at /var/www/vhosts/xxxxxxxxxx/httpdocs/xxxxxxxxxx/wp-includes/plugin.php:507) in /var/www/vhosts/xxxxxxxxxx/httpdocs/xxxxxxxxxx/wp-includes/pluggable.php on line 896"
The x's are mine.
Does anyone have any idea as to how to resolve this? I have had to remove the WooCommerce Plugin folder from the Plugin folder to get the site to function again.
I have also tried a fresh install of the WooCommerce plugin and the same thing happens.
Many thanks in advance for any help
