Allowed Memory Exhausted Errors

Problem

You see the following error:

Allowed memory size of xxxxx bytes exhausted (tried to allocate xxxx bytes)

Cause

WHMCS has reached maximum amount of memory available to PHP on your server.

The memory_limit setting in your server’s PHP configuration controls this.

Troubleshooting

To check the current memory limit setting, go to Utilities > System > PHP Info.

Find the memory_limit directive and note the local value column’s value.

Solution

Increase this setting until the error resolves. We also recommend checking to ensure that you meet all other system requirements.
