Please note apart from cert issues the system is not working. I just spent near an hour writing a detailed guide on Android signing issues for people who were having issues. When i try to post answers it immediately tells me there were errors. I must reload the page and try again. And then all the information is gone.
Currently new wiki pages are created by trying to access a page that does not yet exist. You can either create a link from one page to another that doesn’t exist and then attempt to access the page link or you can type in a URL that does not yet exist. For example: https://wiki.unrealengine/TestPage
Unfortunately the search function no longer provide that feature, since it is now intertwined with the documentation search. We are working on a solution for this, such as a “make page” button. It may take some time to implement
I’m super sorry that happened, I know it’s a crusher when you spend a big chunk of time on writing a thing only to have it disappear into the ether.
This is a poor stopgap solution, but if you use Chrome (this may even be available for other browsers, I just haven’t looked into it.), there is a very useful extension to forestall this very thing, it’s calledLazarus Recovery. I haven’t tried it for the AnswerHub system that we currently use, but I can see the little Lazarus ankh icon on the ‘Ask a Question box’, so it should work.
I hope this helps until we can get your problem resolved. Thanks very much!
