When installed Cite,make sure that the extension is matching the version of mediawiki.

I installed the extension and I meet this error when editing this page:

wfProfileIn() is a function that doesn't exist any more since MediaWiki 1.31. Please make sure to download a recent version of the Cite extension that is compatible with MediaWiki 1.31.
