I just check the max size in phpinfo();
Then check if php.ini is loaded
$inipath = php_ini_loaded_file();
if ($inipath) {
echo 'Loaded php.ini: ' . $inipath;
} else {
echo 'A php.ini file is not loaded';
}
Then Change the upload_max_filesize=2M to 8M
; Maximum allowed size for uploaded files.
upload_max_filesize = 8M
; Must be greater than or equal to upload_max_filesize
post_max_size = 8M
Finally reset your Apache Server to apply the changes
service apache2 restart
