After upgrading our Gitlab CE to version 7.12.2(30bffd5), we cannot “Accept Merge Request” and the green button is always in the spinning status… as shown below.
I used to working on Gitlab CE version 7.7(maybe) installed from source code and everything is perfect, but after upgrading to version 7.12, the feature does NOT work. I’ve tried to re-install (instead of upgrading) this version from source code but nothing different…
Could you please help me to solve the problem? I can provide any information if needed~
