Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi,

My character seems to be bugged. It's a lvl 19 druid, and both in elf-form and bear-form the auto-attack doesn't work. I right-click on the target and I attack once, and then the attack stance is cancelled. This happens every time and I have not experienced this before in the year I play on this server now.

Any ideas on how I can fix this? Thanks in advance.

Edit: it only happens in pvp, in pve it works fine.

delete your WDB folder
