Wordpress LScache Plugin: Fatal Cache error when trying to update product in woocommerce
Last Updated on: Wed, 15 Apr 2026 00:00:02 After updating the litespeed plugin editing products in woocommerce gives an HTTP error 500. Editing prices, weights and quantities resulted in error, but editing pictures and text was successful. Below is the error_log: PHP Fatal error: Uncaught Error: Class LiteSpeed_Cache_Cookie not found in /home/username/public_html/wp-content/plugins/litespeed-cache/includes/class-litespeed-cache.php:135 Stack trace: #0 /home/username/public_html/wp-includes/class-wp-hook.php(298): LiteSpeed_Cache->init( ) #1 /home/username/public_html/wp-includes/class-wp-hook.php(323): WP_Hook->apply_filters(NULL, Array) #2 /home/username/public_html/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #3 /home/username/public_html/wp-settings.php(432): do_action(after_setup_the?) #4 /home/username/public_html/wp-config.php(111): require_once(/home/username/pu?) #5 /home/username/public_html/wp-load.php(37): require_once(/home/username/pu?) #6 /home/username/public_html/wp-blog-header.php(13): require_once(/home/username/pu?) #7 /home/username/public_html/index.php(17): require(/home/username/pu?) #8 main thrown in /home/username/public_html/wp-content/plugins/litespeed-cache/includes/class-litespeed-cache.php on line 135 Any ideas or workarounds? Hi @damien112, You error indicated you didnt update correctly. Please uninstall the current version and install v1.1.4 again. It will solve the issue. Best regards, Hai Thank you for your message! Unfortunately reinstalling the plugin does not resolve the issue. I seem to no longer have the PHP fatal error, but the Error 500 still comes up when litespeed plugin is active. Hi @damien112, Can you give more detail about 500 error? Or you can create a ticket so we can have a look. Thanks, Hai Hi @hailite, Ill mark this thread as solved as I noticed the site isnt using the latest Woocommerce plugin, so it might be an issue. If the issue persists after updating, Ill open up a ticket. Thank you for your support. You are most welcome. If you need any future help, dont hesitate to let us know.
