 * Do you have enough free disk space? (PageSpeed Ninja requires about 1.5 Mb)

 * yes i realized that spaces are over.
 * i installed but unfortunately did not work for me , maybe it is fine for small
   sites but for bigger sites with lots of images and stuff wont work.
 * it breaks my site , can not login at all and not reachable, need to do full restore
 * thanks

 * Thank you for feedback!
 * In next releases we will try to add new settings preset to reduce disk usage (
   with few disabled features: caching, image optimization, and loading of external
   resources) and possibility to choose preferred preset just after the plugin installation.
