Plugin that disables nether portal

Does anyone knows a working PocketMine-MP plugin that disables nether portal? If yes, please give the download link. Because nether portal will make players cannot join the server again (Internal server error) if I install the AlwaysSpawn plugin.

Thanks for your help.

 

what plugins do you have in your server?

 

I have the TableSpoon plugin.

 

TableSpoon is the plugin that active the nether portal you can edit to delete all archive of enderportal
