First thing’s first, this PHP fatal error happened because your server is shared or also because some plugins need a bit higher memory limits to run. And because shared server administrators give specified memory limit to applications like PHP.

If your WordPress encounters PHP fatal error, WordPress first tries to increase PHP memory limit automatically and if it is less than 64MB.
