Hello,
I have created a new project, with the template .gitlab-ci.yml, everything is ok, but the wiki pages option of my project does not appear.
I have also enabled the pages_external_url from the config.rb file of the instance where gitlab is running.
A noteworthy fact, run gitlab in openshift containers
Do you want to enable a wiki for your project? If so, have you followed these instructions Wiki | GitLab?
If you want to enable GitLab Pages, did you set gitlab_pages['enable']=trueGitLab Pages administration | GitLab ? To view the URL of your website you can go to Settings > Pages
