# Activation Causes Internal Server Error

 * Wworks perfectly on dev server, when I move the site to live server (using backupbuddy)
   as soon as I activate plugin, it crashes site with Internal Server error.
 * When site crashes, I’ve tried removing all W3 lines from .htaccess but that does
   not resolve the problem.
 * If I remove plugin, site works again. I tried another caching plugin and did 
   not have the same problem, but I like W3TC best and would like to be able to 
   reinstall.
 * Any ideas? Thank you!
