How to access a wiki page?

I made a wiki page for something I am working on but now I can't access the page anymore. The search thankfully displays the page as the first result. https://gitlab.haskell.org/search?utf8=%E2%9C%93&search=core+representation&... But if I click on the page then it takes me to a UI which asks me to create a new page. This is obviously a bug in gitlab but how can I get to the page anyway? Cheers, Matt
