Gerrit 2.13.5 Submit Button missing for 1 particular branch

[Senthil Kumar]

Submit button is missing for 1 particular branch in a repository. For all other branches in the same repository i can see the submit button.

Am using Gerrit 2.13.5 and log show "Concurrent modification detected" for the CodeReview +2 for a change done on this branch. I thought this issue was fixed in the earlier releases.

Log shows

I sometimes get a 500 internal server error too when doing a review +2 on this for a change on a particular branch. Is this related to Concurrent modification?

Hi, could you try upgrading to gerrit 2.13.9 or 2.14.1 please? Just to see if it was fixed in one of those releases.
