Hello,
Do you have an example of code to demonstrate the problem encountered ?

[Asenar]

I don't have, I got an error when I first configured Thelia, and this changes fixed by problem (but maybe the real problem was elsewhere).

An error can happen when an argument name contains a / , .* or other regex thing.

$url = URL::getInstance()->absoluteUrl('path/to/action', array("cat1/cat2" => "v1", "p3" => "v2"));`
