When I browse as site admin, I get the following warning:
Warning: strpos() [<a href='function.strpos'>function.strpos</a>]: Empty delimiter in /usr/share/tuleap/plugins/webdav/include/webdavPlugin.class.php on line 77
If I add a debug statement L76:
var_dump($http_host.$server['REQUEST_URI'], $webdav_host.$webdav_base_uri);
I get:
string 'tuleap_web_1.tuleap-aio-dev.docker/admin/' (length=41)
string '' (length=0)
It seems there is an issue related to recently fixed bug (see
art #8261)
