Weapon doesn't work anymore

I’m playing in offline mode as Paladin, Act1. Suddenly there is no weapon damage shown in the character overview and I cannot attack although I am holding the weapon. It doesn’t matter which weapon I choose.

Is this a known bug?

Does your weapon need repairing?

Check at the bottom left/right, where you have your skills for left/right click of your mouse.
Is the “attack” skill selected?

Thank you, I didn’t had a weapon skill selected. Sometimes it can be so simple, I think I changed it by accident, so I didn’t pay attention. Thanks again. :grinning:
