How to Increase the PHP memory_limit
A low memory_limit causes "Allowed memory size exhausted" errors. Raising it through the INI editor resolves most of these in seconds.
Step-by-step
- Open Software → MultiPHP INI Editor and choose your domain.
- Find the memory_limit field in Basic Mode.
- Set it to 256M for most sites, or 512M for large stores and heavy plugins.
- Click Apply.
- For WordPress specifically, also add the WP_MEMORY_LIMIT line to wp-config.php — see WordPress memory limit.
- Reload the failing page to confirm the error is gone.
💡 Good to know
- Do not set memory absurdly high to mask a problem — a runaway plugin needs fixing, not feeding.
- Your plan has an overall ceiling; persistent high usage is a sign to discuss an upgrade.
- Check the error log to confirm the error was memory-related.
