anyone know how to fix this error?

Fatal error: The file /XXXX/web/tracker/tsue_install/install.php was encoded by the ionCube Encoder for PHP 5 and cannot run under PHP 5.5. Please ask the provider of the script to provide a version encoded with the ionCube Encoder for either PHP 5.3 or PHP 5.4 or PHP 5.5. in Unknown on line 0

tsue doesn't support php 5.5 as of yet. You will need to downgrade to php 5.4 or re-install your server with php 5.4 etc...
