Friend can't break down blocks (Minecraft 1.7.10 with mods)?

Me and a couple of friends have a MC server on the 1.7.10 with several mods. Actually, everything went up to the one who can't break down to us and wanted to join in but as I said, he can't break down anything…

I would be glad for a good and understandable answer. Thanks

PS: It's not the server and not the game mode.

EDIT: It's not the Spawn Protection.

Maybe it could be because the named person has no OP rights, but the other players who can dismantle?

Hi

Thank you first for an answer but it is not because they can all break down and only I have OP but he does not not with OP.

Ma

I just looked it up on the internet and one person said that it had a similar problem and then set the spawn protection in the server.properties to 0 and that made it work. Would that be the solution?

Ka

I have already tried / tried and it still did not work…

Ma

Are there any mistakes in the startup phase? So any error messages or something?

Ma

Otherwise, which mods are installed?

Ka

There are no errors in the console…

I just do not see any problem mod, but it could actually be that it causes a certain mod. Had seen in a post that someone had difficulties with SinglePlayer Commands and this could not break some people

Okay, okay
