By default, WProofreader uses the 'auto' language, which automatically detects the language while a user typing. In order for the 'auto' algorism to identify the language of the text, there have to be at least three existen words or even more. If the language is not identified, there will be no highlightings.

For troubleshooting, check the proofreading language and type more text if it is 'auto'. If you still suppose that our proofreader doesn't process properly written text, report us via the feedback form.

Note, the 'auto' language might be cached on your side and still be applied even if you specify a new default language on the client-side (product's configuration). So, after making changes, please clean your browser's local storage. To check the language in use you can in the network tab regarding the specific request.
