Wordpress LScache Plugin: Cannot save the LiteSpeed Cache plugin settings
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hi, so I have this problem that I cannot save or change any LiteSpeed Cache plugin settings. I change an option, and I hit Save. But after that when I reload my page, I still see the old settings. I can save other settings inside my wp-admin area (for example I can change core WordPress settings or other plugins settings), but I cannot save the LiteSpeed Cache plugin settings at all. So I cant even turn on debug mode. I read this support page, but it didnt help: https://docs.litespeedtech.com/lscache/lscwp/troubleshoot/#unable-to-save-changes-in-wp-admin I checked and wp-admin isnt cached, and I dont have opcache, memcached and redis enabled. The weird thing is that on this same server I have another WordPress install under a different domain name, with the exact same plugins, settings, and the LiteSpeed Cache plugin works there. I tried to clear all browser cache and cookies. I have even tried it with another web browser, but I still cannot save settings. WordPress version: 5.7.1 LiteSpeed Cache version: 3.6.4 PHP version: PHP 7.4 In another thread I read this: https://wordpress.org/support/topic/options-are-not-saved-3/ please try this : 1. disable plugin 2. go to phpmyadmin , search for litespeed.conf in wp_options tables 3. delete all it finds 4. re-enable the plugin , it will then re-create these deleted entries I havent tried this yet, but I also use the Quic.cloud image optimazation, and I dont want to lose the image optimization data because I have existing optimized images. So what could I do? Hi, it wont , image optm record is stored on different table Best regards, So should I navigate to my wp_options table in phpmyadmin, then search for all rows which begins with litespeed.conf, then delete those rows while the plugin is deactivated? I found 184 rows which begin with litespeed.conf in the wp_options table, for example: litespeed.conf.hash litespeed.conf.auto_upgrade litespeed.conf.api_key litespeed.conf.server_ip etc. should I delete all these 184 rows from the database, from the wp_options table, then re-active the plugin? Are you sure it wont delete my image optimization data? Hi, yes, please delete all these 184 rows yes , disable plugin , delete rows , re-enable it , this will lost other settings , so you can export your current setting first , after you delete the rows , you can import it back if you want to get back your previous setting and refresh the domain key. yes, I am not sure it wont delete img optm data , its stored in wp_litespeed_img_optm table if you are really really so worried , you can just back up the database beforehand : ) Best regards, Thanks for the quick support, it worked! However it is strange, because as I mentioned, I have another WordPress install on this very same server, in the exact same cpanel account, under a different domain name. And on these 2 WordPress sites I have the exact same plugins with the same versions, and of course the configuration is the same, too, because these sites are on the same server (same PHP settings). And one site works, while the another site had this issue (not able to save the plugin settings). And many other users have reported this same issue already, as I browsed this support forum. Seems like the LiteSpeed Cache plugin itself causes some corruption with the stored settings in the wp_options table, and it somehow causes this weird bug that I cannot save any plugin settings. Maybe could you mark this as a bug in the plugin? Hi, yes, I have been tracking this since case 1 , but sadly , we were unable to obtain a reliable way to reproduce it until we can reproduce it , we cant really investigate it how/why/what happened for this issue Sadly I cant reproduce it either. It just happened randomly. Maybe the problem is that somehow even if I save the settings, the plugin doesnt actually update the database table with the updated settings, so that if I refresh the page, I still see the old settings. Hi, yeah , I will keep eye on this , hopefully can have a way to reproduce soon best regards, I still experience this bug on yet another domain. Maybe the problem is that by default Cache Wp-Admin is set to ON . And maybe when you cache wp-admin, this can cause this behavior than I cannot save the settings? Are you sure that it is necessary to cache the wp-admin by default? I think you should not cache the wp-admin by default, it can cause more harm than good. On another domain I set the Cache Wp-Admin to OFF, and now I dont experience this error anymore. But first I had to delete the litespeed cache rows from the database. I dont see any reason why should we ever cache the wp-admin? We stumbled upon the same problem. Litespeed is for some reason unable to show settings as they are saved in the database. It just shows defaults. Changing any setting does update the setting in the database, but litespeed settings pages will still show the default settings after page reload. After deleting all litespeed tables the problem went away.
