Memory exhausted errors occur when a script tries to use more PHP memory than the configured limit allows, usually because of large imports, image processing, backups, or inefficient code.
Common symptoms
- Fatal error Allowed memory size exhausted
- Only specific pages fail
- The issue appears during imports or plugin operations
Troubleshooting steps
- Identify the exact script or plugin named in the error log.
- Reduce the size of the task if possible, such as importing in smaller batches or optimizing images before upload.
- Disable non-essential plugins and retest the failing action.
- Confirm the active PHP version and plugin stack are supported and up to date.
- If your hosting plan and application support it, adjust memory settings through the approved control in cPanel.
Additional notes
- Raising limits without understanding the workload can mask the real problem temporarily.
- Image manipulation and backup plugins are common memory consumers.
