Problem Description:
There doesn't appear to be any permission to prevent blocks from taking damage from explosions (creepers and other monsters that cause explosions). I looked through the entire permission list and here's what i use in my region config:

"groupPermissions": {
"ALL": {
"fe.protection.explosion": "false",
"fe.protection.damageby.": "false",
"fe.protection.pvp": "false",
"boss": "false",
"hostile": "false",
"fe.protection.break.": "false",
"fe.protection.place.": "false",
"fe.protection.mobspawn.natural.": "false",
"fe.protection.interact.BiblioCraft.BiblioFancySign.": "false"
},
"members": {
"fe.protection.interact.Mekanism.MachineBlock2.4": "true",
"fe.protection.interact.Mekanism.MachineBlock.5": "true",
"fe.protection.interact.Mekanism.MachineBlock.6": "true",
"fe.protection.interact.": "true",
"fe.protection.interact.Mekanism.MachineBlock.13": "true",
"fe.protection.interact.Mekanism.MachineBlock.8": "true",
"fe.protection.interact.Mekanism.MachineBlock.15": "true",
"fe.teleport.tpahere.sendrequest": "true",
"fe.protection.interact.BiblioCraft.BiblioFancySign.": "false"
},
"mods": {
"fe.protection.interact.Mekanism.MachineBlock2.4": "true",
"fe.protection.interact.": "true",
"fe.teleport.tpahere.sendrequest": "true",
"fe.protection.interact.BiblioCraft.BiblioFancySign.": "false"
},
"admins": {
"fe.protection.break.": "true",
"fe.protection.interact.": "true",
"fe.protection.place.": "true",
"fe.teleport.tpahere.sendrequest": "true",
"fe.protection.interact.BiblioCraft.BiblioFancySign.*": "false"
}

Was explosion prevention removed or am i missing something?

The only solution will be to change the /gamerule mobgriefing false. This should give you a direction of what you need. @Ruok2bu
