For Shared and Reseller customers you can easily do this in cPanel by taking the following steps:

  • Log into your cPanel account
  • Under the “Software / Services” section, click on “Select PHP version
  • On the right hand side, click the link that says “Switch To PHP Options”. If this says “Switch To PHP Extensions” then you are already in the right spot
  • Click the gray setting next to the following option:“memory_limit” – A drop down will appear and allow you to change the memory allowance per PHP process.
  • Click “Save

For VPS / Dedicated customers:

  • Log into WHM as root.
  • Click on “PHP Configuration” under the “Service Configuration” menu
  • Fill in the circle next to “Advanced Mode
  • Scroll down and look for “memory_limit”.  You can change this variable to anything you want however you should never exceed the amount of your server. In most cases, 128M will be fine.
  • Click “Save” at the bottom and make sure to restart Apache by clicking “HTTP Server (Apache)” in the left menu under “Restart Services”.
