TCPDF ERROR: Unable to create output file: myfile.pdf
In the include/tcpdf_static.php file about 2435 line in the static function fopenLocal if I delete the complete 'if statement' it works fine.
public static function fopenLocal($filename, $mode) {
/*if (strpos($filename, '://') === false) {
$filename = 'file://'.$filename;
} elseif (strpos($filename, 'file://') !== 0) {
return false;
}*/
return fopen($filename, $mode);
