I install litespeed free edition, install WHM addon, update PHP to match with Apache's and "switch to Litespeed". No errors. But i am still not sure whether i am using litespeed, because: 1) It says both apache and litespeed are running: [LiteSpeed is running (PID = 21614). Apache is running (PID = 26111). ] 2) When I install one drupal site, it asks to install apache add-on [Operations on Unicode strings are emulated on a best-effort basis. Install the PHP mbstring extension for improved Unicode support.] let me know how do i check whether i am running on apache or litespeed. So far so smooth if it is running litespeed , ready to buy VPS version. Incase if you want to check, site is fortunesindia(dot)com Thanks, Seems like there is some problem: I have this error on admin console: Apache Binary Path must be set properly in order replace Apache, fall back to 'Reload on configuration file change'.
