Error 500 on modules

[loderx]

When try to open modules give me error 500
Declaration of MultiBlockAtoh::unregisterHook($hook_id) should be compatible with ModuleCore::unregisterHook

[musicmaster]

Which file produces the error?

[datakick]

The problem is with module 

MultiBlockAtoh

You need to delete it from /modules/multiblockatoh or modify it -- change signature of method 

unregisterHook

so it looks something like this:

public function unregisterHook($hookId, $shopList = null) 
{
  ...
}
