Melee Attacks Not Working


I’ve been having issues on various ranged/caster characters (the ones where melee is not the main attack type like druid or hunter) and am unable to utilize any of my melee weapons. I have a toon at level 10, almost 11, and have looted and purchased higher level weapons than the starter ones but that still doesn’t fix the issue. It is super frustrating not being able to defend these characters in close combat properly as their spells or skills get interrupted by enemy melee.

I have downloaded WoW through the Bnet launcher and am playing on the trial account. Any help would be great.
