Mop Bug Mage Pet

Hello,
I’m having a problem with my mage’s pet; it remains completely passive.
The /petattack command isn’t working (although it did yesterday).
Whether it’s in macro form or by clicking on the pet bar, nothing works, my pet remains 100% passive.
And regardless of its status (defensive, assistive, passive),
Can someone help me?
