Step 3: Open PHP Options

This will show the PHP settings available for your account.

Common PHP settings

You may see options such as:

• memory_limit
• upload_max_filesize
• post_max_size
• max_execution_time
• max_input_vars
• display_errors

The exact options available may vary depending on the server and PHP version.

Step 4: Change the required setting

Click the value you want to change and select or enter the new value.

For example, if a WordPress theme or plugin requires a higher upload limit, you may need to increase:

• upload_max_filesize
• post_max_size

If a WordPress plugin or large import is timing out, you may need to increase:

• max_execution_time
• memory_limit

Important notes

Only increase PHP limits where needed.

Very high limits may not improve performance and can sometimes cause other issues.

Some settings may be limited by the hosting plan or server configuration.
