Common Issues and Troubleshooting<\/h2>\nWHM Shows “LiteSpeed is Not Running” After Switching from Apache<\/h3>\n Cause:<\/strong> Port 80 is still bound by Apache after the switch. LiteSpeed can’t start because the port is already in use. This happens when the switch-to-lsws script completes without fully stopping Apache first.<\/p>\nFix:<\/strong> Stop Apache manually, confirm the port is free, then start LiteSpeed:<\/p>\n<\/path><\/path><\/svg><\/path><\/svg><\/button>Copied to clipboard<\/span><\/p>\nsystemctl stop httpd\nss -tlnp | grep ':80'\n\/usr\/local\/lsws\/bin\/lswsctrl start<\/code><\/pre>\n<\/div>\nIf ss<\/code> still shows something on port 80 after stopping httpd, check for a stale PID file:<\/p>\n<\/path><\/path><\/svg><\/path><\/svg><\/button>Copied to clipboard<\/span><\/p>\ncat \/usr\/local\/lsws\/logs\/lshttpd.pid\nrm -f \/usr\/local\/lsws\/logs\/lshttpd.pid\n\/usr\/local\/lsws\/bin\/lswsctrl start<\/code><\/pre>\n<\/div>\nPlugin Disappeared from WHM After a cPanel Update<\/h3>\n Cause:<\/strong> cPanel updates occasionally overwrite or reset plugin registrations, especially major version jumps (e.g. 110 to 118). The LSWS files are still on disk but WHM no longer knows about them.<\/p>\nFix:<\/strong> Re-register the plugin without a full reinstall:<\/p>\n<\/path><\/path><\/svg><\/path><\/svg><\/button>Copied to clipboard<\/span><\/p>\ncd \/usr\/local\/lsws\/admin\/misc\nbash plugin_update.sh<\/code><\/pre>\n<\/div>\nIf that script doesn’t exist, run the full installer from step 2 above \u2014 it’s safe to run on top of an existing installation and won’t wipe your LSWS configuration.<\/p>\n
\ud83d\udcdd Note: I’d recommend adding the plugin reinstall to your post-update checklist if you’re running LSWS on a managed server. cPanel’s EasyApache 4 updates are the most common trigger for this.<\/p>\n
“PHP Handler Not Set to LiteSpeed” Warning in WHM<\/h3>\n Cause:<\/strong> PHP is still configured to use Apache’s mod_php or CGI handler. LiteSpeed has its own SAPI (Server Application Programming Interface) \u2014 if PHP wasn’t rebuilt after LSWS was installed, you lose most of LiteSpeed’s performance benefit.<\/p>\nFix:<\/strong> In WHM, go to Software > EasyApache 4<\/strong>, click Customize<\/strong> on your current profile, and ensure the LiteSpeed SAPI<\/strong> package is selected for the PHP versions you’re using. Save and provision the profile. Then return to WHM > LiteSpeed Web Server and click Build PHP<\/strong>.<\/p>\nVerify it worked:<\/p>\n
<\/path><\/path><\/svg><\/path><\/svg><\/button>Copied to clipboard<\/span><\/p>\nphp -i | grep 'Server API'<\/code><\/pre>\n<\/div>\nYou should see Server API => LiteSpeed<\/code>. If you still see CGI\/FastCGI<\/code>, the rebuild didn’t complete \u2014 check \/usr\/local\/lsws\/logs\/error.log<\/code> for details.<\/p>\nLiteSpeed Cache Plugin Conflicts Causing 500 Errors on WordPress Sites<\/h3>\n Cause:<\/strong> The LiteSpeed Cache WordPress plugin (LSCache) relies on server-side cache rules that need to be set at the LSWS level. If those rules aren’t in place \u2014 or if another caching plugin like WP Rocket or W3 Total Cache is active at the same time \u2014 you’ll get cache header conflicts that produce 500 errors or blank pages.<\/p>\nFix:<\/strong> First, confirm no other caching plugin is active in WordPress. Then check whether the cache root is correctly defined in LSWS:<\/p>\n<\/path><\/path><\/svg><\/path><\/svg><\/button>Copied to clipboard<\/span><\/p>\ngrep -r 'cacheRoot' \/usr\/local\/lsws\/conf\/<\/code><\/pre>\n<\/div>\nIf nothing returns, the cache root isn’t set. In WHM > LiteSpeed Web Server > Cache Manager, set the cache root to \/tmp\/lscache<\/code> or a path on fast local storage. Restart LSWS after saving.<\/p>\n\u26a0 Warning: Don’t set the cache root to an NFS-mounted path. LiteSpeed cache writes are frequent and small \u2014 NFS latency will make this dramatically worse than no cache at all.<\/p>\n
Licence Reverts to Trial Mode After Server Migration<\/h3>\n Cause:<\/strong> LiteSpeed licences are tied to the server’s IP address. After a migration \u2014 including IP changes on Host & Tech VPS or dedicated servers \u2014 the licence validation fails silently and LSWS falls back to a 2-worker trial mode, which caps concurrent connections.<\/p>\nFix:<\/strong> Log into your LiteSpeed account at https:\/\/store.litespeedtech.com<\/code>, release the licence from the old IP, and reissue it to the new IP. Then on the server:<\/p>\n<\/path><\/path><\/svg><\/path><\/svg><\/button>Copied to clipboard<\/span><\/p>\n\/usr\/local\/lsws\/bin\/lshttpd -r<\/code><\/pre>\n<\/div>\nThis forces a licence refresh. You should see the worker count increase in the LSWS admin panel (default port 7080) under Server Status<\/strong>.<\/p>\nFAQ<\/h2>\n\n
Frequently Asked Questions<\/h2>\n\n
How do I switch back to Apache from LiteSpeed in WHM?<\/h3>\n\n
In WHM, go to Plugins > LiteSpeed Web Server and click ‘Switch to Apache’. This runs the built-in switchback script and restarts the web service. If the UI option isn’t available, run \/usr\/local\/lsws\/admin\/misc\/switch2apache.sh as root over SSH. Verify Apache is running with systemctl status httpd afterwards.<\/p>\n<\/div>\n<\/div>\n
\n
Why is LiteSpeed using only 2 workers after installation?<\/h3>\n\n
Two workers means LSWS is running in trial or unlicensed mode. The licence is either missing, expired, or tied to a different IP. Check \/usr\/local\/lsws\/bin\/lshttpd -v to see the licence status. If the IP changed recently \u2014 such as after a server migration or network reconfiguration \u2014 you’ll need to reissue the licence from your LiteSpeed account.<\/p>\n<\/div>\n<\/div>\n
\n
Does the LiteSpeed plugin work with cPanel multi-PHP configurations?<\/h3>\n\n
Yes, but each PHP version needs to be individually rebuilt with LiteSpeed SAPI via EasyApache 4. It’s a common mistake to rebuild only the primary PHP version and leave the others on CGI. Go to WHM > LiteSpeed Web Server > Build PHP and make sure all active PHP versions are included in the build.<\/p>\n<\/div>\n<\/div>\n
\n
Can I run OpenLiteSpeed and the WHM LiteSpeed plugin together?<\/h3>\n\n
No \u2014 the WHM plugin is designed for the commercial LiteSpeed Web Server (LSWS), not OpenLiteSpeed. They’re separate products with different configuration formats and admin interfaces. Using the WHM plugin installer on a server running OpenLiteSpeed will produce errors and may corrupt the existing OLS setup.<\/p>\n<\/div>\n<\/div>\n
\n
How do I check the LiteSpeed error log in WHM?<\/h3>\n\n
The main LSWS error log is at \/usr\/local\/lsws\/logs\/error.log. You can tail it in real time over SSH with: tail -f \/usr\/local\/lsws\/logs\/error.log. Per-domain logs are usually in \/home\/username\/logs\/ if virtual host logging is enabled. The WHM plugin UI doesn’t expose log viewing directly \u2014 SSH is the fastest way to dig into errors.<\/p>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
