You can raise PHP limits from cPanel's MultiPHP INI Editor:
- Log in to cPanel and open MultiPHP INI Editor under Software.
- Select your domain (or location).
- Adjust values such as:
upload_max_filesize(e.g.64M)post_max_size(set equal to or higher than upload size)memory_limit(e.g.256M)max_execution_time(e.g.120)
- Click Apply.
Some accounts can also use a Select PHP Version > Options screen, or add directives to .user.ini / php.ini in public_html. Note that your hosting plan sets a maximum ceiling, so very high values may be capped. If a setting will not stick or you need a higher limit than the editor allows, open a ticket and let support know the values you need.
