Hi
I just upgraded from 13.2 to 13.9, docker version. Everything was OK. But…
The job page does not look fine. I have:
An error occurred while fetching the job log.
The avatar and the log are gone (black screen)
Any idea?
Hi @bonzo , welcome to the GitLab Community Forum! 
As a good first step in troubleshooting, I propose we run a gitlab-ctl reconfigure and gitlab-ctl restart to ensure that everything was migrated, cache cleared, configuration
applied, and components restarted.
For example
docker exec -it gitlab gitlab-ctl reconfigure
docker exec -it gitlab gitlab-ctl restart
After about 1 minute when GitLab comes up, can you verify if the problem persists?
If the problem is still occuring, I suggest running gitlab-ctl tail to view the GitLab logs in real time while reproducing the problem in the UI. The GitLab logs will capture details that are very helpful in troubleshooting.
You might also consider running some basic checks on your system like gitlab-rake gitlab:check SANITIZE=true
Thx for ur answer.
Running:
gitlab-rake gitlab:storage:migrate_to_hashed
Solved the problem.
