Wordpress LScache Plugin: The plugin overwrites WPs delete_transientwith incompatible API.
Last Updated on: Wed, 15 Apr 2026 00:00:02 The problem surfaced when LiteSpeed Cache (LSC) was run together with Google Listings and Ads (GLA) plugin: https://wordpress.org/support/topic/fatal-error-3907/. GLA uses WordPress method delete_transient, which is expected to return bool https://github.com/WordPress/WordPress/blob/6acd4d4c16efc0b86aa240329ec6fd60762d1435/wp-includes/option.php#L760-L762 However, LSC happens to overwrite the cache with something that may not necessarily return bool. We will work around it in GLA by typecasting. But I guess a similar issue may also unexpectedly surface with other plugins. Thanks @tomalec Thank you for pointing this out. Good point. I will forward it to our dev team and see how they would like to get a better compatibility on this. Regards, Abe
