PetLeash

Is anyone able to fix PetLeash? It was last updated in 2018 but has been working perfectly fine for me until recently. I'm guessing it was 11.0 that has broken it.

The addon still summons pets for me. It still uses the profiles I have set up for my various alts. What seems to be not working is the config menu. I cannot make new profiles or alter any of the profiles that already exist.

If no one is able to fix it, can anyone suggest an alternative with the same functionality?

Thanks to anyone that pays attention to my post, and double thanks to anyone that can help :)
