Bibliography style

Dear Community,

up to now I had that citation style 


“xxxx” (1) 

 2. Bibliography

  1. Ptok M, Ptok A. [Laryngopharyngeal reflux and larynx-related symptoms]. Hno. 2012;60(3):200-5.

I do not know the reason, but recently without me knowing about changing any settings, it is like 

“xxxx” [Ptok M, Ptok A.Laryngopharyngeal reflux and larynx-related symptoms Hno. 2012;60(3):200-5.]

How can I change it back to work with references?

Thank you a lot!


I don’t understand this particular post or the problem.  Is it related to the other one?
