The default upload size in the cpanel is 2MB. This means, when you try to upload a file greator than 2MB, you’ll receive an error. But most of the times, files uploaded are greator than this. So here’s how you increase the size using php.ini file.
1. Access the cpanel and scroll down to MultiPHP INI
2. Select the location of php.ini file in the drop down menu. Select your domain name as the location. If you are working on a subdomain, select the subdomain as the location of php.ini file.
3. Alter the upload_max_filesize variable and click Apply.
