Wordpress LScache Plugin: Failed to delete: There was a critical error on your website
Last Updated on: Wed, 15 Apr 2026 00:00:02 Dear LiteSpeed Team, I had Problems with the Domain Key Settings on a WordPress Multi-site. So I tried to de-install you Plugin. But when I did, there came the error Message: Failed to delete: There was a critical error on your website, learn more about troubleshooting WordPress. And the plugin still exists. No other Problems on the website accrue. Then I deleted the Plugin Folder. And reinstalled your Plugin. But even then it is impossible to de-install it on the multi site network level afterwards. Do you have any Idea? Regards, Willi. The page I need help with: https://www.magic-show.info/ The reason why i wanted to uninstall the plugin: I have a Multisite WordPress installation. When in Enable your Plugin network wide, I can not set my domain key. When I enable you plugin on a single site, i can set the domain key properly. But than I can not set the page cache and the browser cache, because therefore I have to activate the plugin on the network level. I I enable the plugin on both network level and site level, then I have the problem with the domain key again. Any solution for this? Hi, When in Enable your Plugin network wide, I can not set my domain key Do you see any error message when you try to get domain key ? Best regards, These are the messages: Notice: Please wait. You will be notified upon approval. and than: Warning: You must have Domain Key first before linking to QUIC.cloud. ? And when I change something on the Page Optimization everything falls back after I saved and refreshed the site. Hi, Please wait. You will be notified upon approval. yes, this is normal message, and after few minutes , you should have the domain key , or you just dont see it ? and also please check this doc Best regards, No, I definitely do not have it. The field is empty. There is no and still the Warning: You must have Domain Key first before linking to QUIC.cloud. And not possible to save the Page Optimations Settins. The Validate sais 404 ? all good. https://www.magic-show.info/wp-json/litespeed/v1/ip_validate But that does not change the problems above. Hi, Could you please provide the report number ?
