Thanks! May 19, 2020 at 9:46 am #1292344 TomLead Developer Lead Developer Hi there, Are you seeing any errors on the front-end, or is this just in the logs? That line contains this code: if ( ! WC()->cart->is_empty() ) { $has_items = ' has-items'; } That’s the current best way to check if the cart is empty – your error looks like it’s saying the WooCommerce WC() class doesn’t exist. Are you using any caching plugins/server caching? May 21, 2020 at 3:08 am #1295079 Deniz Akay It is just in the woo logs, I don’t see any errors on front end. And yes I’m using fastest cache plugin. May 21, 2020 at 9:42 am #1295685 TomLead Developer Lead Developer I’m assuming that the cache is preventing WooCommerce from fully initiating, so that class ends up not having any value. We’ll add some safeguards into GPP to prevent the errors in the logs. Author Posts Viewing 4 posts - 1 through 4 (of 4 total) You must be logged in to reply to this topic.
