Topic on Extension talk:MagicNoCache

I try to use it on mediawiki 1.31 but it does not work.

I have $wgUseFileCache = true;

what was the error?

I do not think it makes sense to use file caching and this extension at the same time. File caching means that a static copy of a given page is saved in the cache directory. I am not sure if the behaviour switch causes the page not being saved in the first place.
