 * Hi, 
 * After a few hours I installed the LiteSpeed Cache plugin, my website is not loading
   anymore and the cpanel shows me 99% CPU usage. As soon as I delete the LiteSpeed
   Cache plugin, CPU usage goes back to 0.  I have to say that the crawler is not
   enabled and I have tried to repair the database with repair.php and I still have
   the same problem.  ( https://docs.litespeedtech.com/lscache/lscwp/troubleshoot/#
   database-corruption )I have deleted the website from quick cloud now, but I believe
   it is something with image optimization. Even if it is off in the LiteSpeed Cache
   plugin setting in quick cloud show me 100% quota to image optimization. 
 * Any recommendations? Thank you!

 * if you enable plugin , but keep image optm OFF , how does that go ?
 * you can just go to Image optm setting , set first 2 options to OFF , and then
   click “clean up unfinished data” , this should render image optm inactive.

 * then it’s probably not related to image optm
 * if you go to toolbox -> import/export -> reset to default setting , how does 
   that go ?

 * Same.
   But don’t worry. I don’t need support anymore. I have changed to another
   cache plugin. Thank you!
