Found during running make download for site, UK language.

Using relative link (https://www.php.net/manual/en/function.PDOStatement-setFetchMode.php) but repoUrl is not set.

Interesting. The link is definitely not relative.

Yep, need to recheck #256. Not critical though, as I see.

@arogachev api mark all absolute links as relative when $repoUrl is not set:
