Can you help?

 

Code:

THIS CRASH WAS CAUSED BY A PLUGIN

 

I saw that, but I don't know which plugin.

 

Code:

#1 /Slapper/src/slapper/entities/SlapperHuman(65): spl_autoload_call(string pocketmine\network\protocol\AddPlayerPacket)

 

What can I do to fix this? I need the Slapper plugin for my server.

 

If it's the default Slapper plugin, without any modifications, than you can create an issue in the Github repository.

 

But it worked pefectly before. Is this because of the api3/network branch? And that the 1.0.5 is not out yet?

 

Slapper may not support the API version in that branch. You'll need an updated version for it to work (you may also get by just by bumping the API in the plugin.yml, but that doesn't always work).

 

Will it work when PMMP for 1.0.5 will come? Plus, where can I get a newer version for Slapper?

 

I'm afraid that I have no way of knowing. Although you can always get the latest slapper from the Slapper Github repository. Do note that just because it's the latest version of the plugin, doesn't mean it will support the latest version of PocketMine, or the latest version of the PocketMine API.
