 * It means that server ran out of memory. Probably you need more RAM.

 * Thanks…

 * Hi,
 * I had this problem in the past and I’m using the premium version. I increased
   my RAM to 2GB. Because 1GB may not be enough especially when you have a large
   database or a lot of post and pages. When the prebuild cache is running, it may
   cause some random timeouts you may also try to adjust the prebuild speed to reduced
   if you are on a shared hosting. Another suggestion is that PHP version should
   be at 7.2. WordPress version 5.2. I’m just sharing these based from my experience.
   I’m using three sites under this plugin. 1 of them using the free lite version
   and the other two with the premium version. So far after these upgrades I never
   experienced any timeouts at the backend.
