Since a very recent version, autolinks do not appear if they are inside a wiki article. This is because the wiki parser now uses a variation on the BB-Code tag list that autolinks no longer understand.
This can cause potential issues with other custom BB-Codes, so a clone of the old tag list will be added for the next build.
Until then you can fix this in the file
vault/special_class_bbcode.php. Find:
PHP Code:
$new_tag_list = array();
Replace with:
PHP Code:
$new_tag_list = $this->tag_list;
