Server Problems

Hey everyone. I'm playing on a new Aternos server that I created (today). I'm having a slight problem! So. I have OP in my server. No one else has joined it except me, since its creation. Basically, whether I'm in creative or survival, I cannot pickup items off the ground into my inventory. I can equip items just fine, but I can't pickup anything. I'm on MC 1.15.2, and my server is on Software PaperMC.

If you guys want a list of my plugins, I'd be glad to give it.

Thank you!

Hey. So, yep. It's a problem with my plugins! I went into the server with plugins on, and I couldn't pick anything up, still. (And, for some reason, even though I was in survival, mobs wouldn't attack me, but that's a separate issue) I loaded it into Vanilla, and I could pick items up, and mobs attacked me. Should I give you a list of my plugins? I'd be happy to do so!

Thanks again.
