Hola, tengo una pagina web con el modulo de ajedrez CompWebChess
que da error al ejecutar javascript (al intentar mover las piezas).
Lo curioso es que en mi pc, en modo local, si que me funciona.
Hay que tener algo en cuenta al subir los ficheros a miarroba en
el caso de javascript ?

La pagina es http://lacolmena.webcindario.com

Gracias.

Al cargar la pagina me da los siguientes errores:
