With solution

Language guessing and realurl

Language guessing does not always work when the language parameter is translated with old versions of realurl.

Solution: Update realurl to at least version 1.12.8

Extension cooluri

By default, cooluri handles 404 errors itself.

Solution:

Configure cooluri to use the default TYPO3 404 handling. Luckily it provides this option itself, you just have to uncomment it in CoolUriConf.xml:

<cooluri>
    <cache>
        <pagenotfound>
            <behavior type="userfunc">Bednarik\Cooluri\Integration\Cooluri->pageNotFound</behavior>
        </pagenotfound>
    </cache>
</cooluri>
