Hello I have just recently installed EchoPets. i was typing in the commands to get a pet, then it said that EchoPets 2.6.0 was not compatible, and I needed to update. I need help!

See #503

This is what it says, I checked the link you provided, but I am still confused.. Do I need Spigot instead of CraftBukkit?

I'm assuming you're running 1.8.3, a server version which no public release of EchoPet is compatible with (yet). If you're interested in running mostly stable development builds which are compatible with 1.8.3, you can acquire them at the above link (direct CI link here).

Spigot/CraftBukkit doesn't matter :).

Oh okay, but the weird thing is, that my CraftBukkit is 1.8.0 not 1.8.3 o:

It shouldn't show that for 1.8 :o

Hello once again, I am so sorry for wasting your time, but I recently checked my server, it is 1.8.3 it's my fault, I am so sorry for wasting your time again! :) I feel really bad now, i could have sworn it was a 1.8.0 server. Sorry for wasting your time once again!

No problem at all. I'm happy to help if you come across any issues again :).
