I think you fixed this but just in case.... you may have accidentally set the SilkSpawner permission "spawnEggToSpawner " to "true" on Skyblock. The permission you probably intended to set true is called -silkspawners.changetypewithegg.* Also when you place a spawner that has been mined it goes back to the default pig spawner. The permission silkspawners.place.* or silkspawners.place.<creaturetype> should be "true" and all normal creature types set to "enabled".
I still get that error message "You do not have permission to change spawners with a spawn egg". On the plus side spawn eggs are working normally when spawned on the ground now And I was incorrect about silkspawner.place being turned off. The problem placing spawners has something to do with the minecraft item tags. If the monster spawner has a tag 1 it will give an error message when placed and revert back to the default pig spawner. If it has a tag 3 it can be placed and retain it's creature setting. Sending a spawner threw the auction can change the tag from 3 to 1. Also, only spawners with tag 1 can be sold in a chestshop. After you buy it and it's in your inventory it will display the modified creature setting but when it's placed it will go back to the default pig spawner. I did some googling and found out that silkspawner and chestshop together have a few bugs. Thanks for all your help!
I just thought of something. Did you change the permission for oped players but not not regular players? That might be why it's working for you and not me.
