 * Hello,
    thanks a lot for reporting that error. After 140 downloads no one did
   it but you :D. This is my fault i forgot to put the isMU() function into the 
   plugin because it’s already in my other plugin so I didn’t have the issue while
   testing. Just install the new release 0.2.3 to fix the error.
