Wordpress LScache Plugin: v4.2 is ready
Last Updated on: Wed, 15 Apr 2026 00:00:02 It is on master branch of our Github repo. You can use Toolbox -> Beta Test to give it a try. Note: upgrade only from v3.6.4+ to v4.2. Lower versions will result in an upgrade error. The error wont cause any issue for your sites. Just the plugin itself will be deactivated by WP when WP detected any error. You will need to manual activate the plugin again if upgrade from v3.6.3- to v4.2. Enjoy the new Guest Mode option. You dont have to manually tune the page optimization settings back and forth anymore. The new version v4.2 is already on WP. However, as this version contains substantial changes, the latest stable version on WP will keep on v3.6.4 for a while. V4.2 is scheduled to mark as the latest stable version on WP at Aug/11/2021. Here is the changelog: = 4.2 ? Jul 29 2021 = Cloud Auto redirect to a new node if the current node is not available anymore. Cloud Combined CCSS/UCSS to sub services of Page Optimization. Cloud Added a daily quota rate limit to help mitigate the heavy service load at the beginning of the month. Cloud Cached the node IP list in order to speed up security check. (@Lucas) GUEST Fixed an issue where Guest Mode remained enabled even when the UA setting is empty. (@Stars) GUEST Guest Mode will no longer cache POST requests. UCSS Purging CSS/JS now purges the UCSS queue as well, to avoid failure when generating UCSS. UCSS Separated service entry UCSSfromCCSS. CCSS Simplified load_queue/save_queue/build_filepath_prefix functions. ( Contributed by Alice Tang #PR373) CCSS If CCSS request fails, details are now saved in the CSS file. CCSS Renamed CCSS ID in inline HTML from litespeed-optm-css-rules to litespeed-ccss. (@Alice) Page Optimize CCSS/UCSS now supports Cloud queue/notify for asynchronous generation. Page Optimize Simplified CCSS/UCSS generation function. Page Optimize Added the ability to cancel CCSS/UCSS Cloud requests.

API Added shorter alias litespeed_tag and other similar aliases for Cache Tag API. API Renamed LITESPEED_BYPASS_OPTM to LITESPEED_NO_OPTM for Page Optimization. Toolbox Dropped v3.6.4- versions in Beta Test as they will cause a fatal error in downgrade. GUI Added shortcut links to each section on the Dashboard. GUI Added UCSS whitelist usage description.

(@Ruikai #371) Request some advice specially for Buddypress users We had an issue in the past with Avatars, passwords and Buddypress Profile Editing with caching. We saw that in support over a year back you had given another version of the plugin. is 4.2 fully compatible with Buddypress ? Kindly share the right settings for Buddypress website with blogs and User Profiles ( user profiles are regularly updated, many X profile fields are there too and are updated) Please advise which AMP works with this plugin Would you advise any Progressive Web apps so one can use it better on Mobiles too Thank you ! Hi, I noticed the new plugin update today and I have a few questions: 1. Should I update it now? It says its not been tested with WP 5.8. I got Litespeed 3.6.4 installed. and my server is on Litespeed server ? Anything else I need to think of before updating? 2. The changelog says that the last changes were made in July, is this correct? So no new changes for a few weeks? 3. This is a bit off-topic, but I have problems with WPForms. It says that it has detected an issue with JavaScript on this page. JavaScript is required for this form to work properly, so this form may not work as expected . After googling around, it seems its an issue for other Litespeed servers. What should I do to make sure people can send forms? Looking forward to your reply, Kind Regards Espen @mpcd108 Buddypress compatibility is in todo. @passion4fm 1. You can. The only known WP 5.8 compatibility issue is the widget ESI settings. That is why we didnt mark it as tested up to WP5.8. 2. You are right. V4.2 was packed at that moment. The newer improvements are in dev branch only. You can test them by Beta Test too. But the official v4.2 wont have any changes since packed in July. 3. JS related issue, you can follow our doc to debug. In v4.2, you can turn off all manual JS optm, only use Guest Mode. is there any version of LiteSpeed Cache which is good for Buddypress ? then i can use it for now.
