PHP Fatal error: Uncaught Error : Call to undefined function LiteSpeed\litespeed_oc_disable_ext_cache() in public_html/wp-content/plugins/litespeed-cache/src/object-cache.cls.php:586 Stack trace: #0 public_html/wp-content/plugins/litespeed-cache/src/object-cache.cls.php(444): LiteSpeed\Object_Cache->_connect() #1 public_html/wp-content/plugins/litespeed-cache/src/object-cache.cls.php(389): LiteSpeed\Object_Cache->_reconnect() #2 public_html/wp-content/plugins/litespeed-cache/src/activation.cls.php(338): LiteSpeed\Object_Cache->update_file() #3 public_html/wp-content/plugins/litespeed-cache/src/activation.cls.php(82): LiteSpeed\Activation->update_files() #4 public_html/wp-includes/class-wp-hook.php(341): LiteSpeed\Activation::register_activation() #5 public_html/wp-includes/class-wp-hook.php(365): WP_Hook->apply_filters() #6 public_html/wp-includes/plugin.php(522): WP_Hook->do_action() #7 public_html/wp-admin/includes/plugin.php(703): do_action() #8 public_html/wp-admin/plugins.php(60): activate_plugin() #9 {main} thrown in public_html/wp-content/plugins/litespeed-cache/src/object-cache.cls.php on line 586 Maybe since I disabled redis or active version 7 worpress Do you know why ? Thanks a lot please try , use phpmyadmin , go to wp_options table , find option litespeed.conf.object , set value to 0 , then try to activate plugin , see if you still get this error. Hello, It’s works thanks you, I’m able to activate the plugin again. but anytime I’m trying to configurate REDIS inside the plugin it’s say : Extension Memcached : Activé(e) Extension Redis : Activé(e) Test de connexion: Échouée I have the plugin Redis Object Cache and it’s say : well connected Thank you for your help Test de connexion: Échouée translate shows “standard” , I am not sure what does that mean , I assume it means error ? make sure you set correct host/port/DB/user/pass for Redis oups sorry : Connection test : Echec I have set correctly the information, like before, but i changed the password. I will try to ask to the support of my hosting Thanks you
