cannot submit scores - Call to undefined function - latest ibproarcade

When submiting new score I get a blank page with this error

Fatal error: Call to undefined function: stripos() in /home/admin/domains/doodsaai.nl/public_html/forum/arcade.php on line 3498

Running latest version of IBProArcade

you are using PHP4, re-download the archive and replace /arcade.php and everything is fixed
