Some more information if it can help. The setup on which the issue occurs is based on
* PHP 7.0.7, MySQL 5.6.33
* Joomla! 3.7.5 Stable (installed automatically by my host)
* VirtueMart 3.2.4 (Installed as part of the QUARK - manual installation steps)
* Multi-lang configuration: French (default) & English
When I setup QUARK using the quickstart installation steps I don't observe the issue.
I noticed that the versions differ from my setup (VirtueMart 3.0.18, Joomla 3.7.0). The VirtueMart 3.0.18 release is fairly old (2016).
Is QUARK expected to be supported for the latest versions of VirtueMart ?
Assuming it is, I have done some more experimentations on the setup facing the issue. I used the VirtueMart tools in order to wipe the tables and re-install the VirtueMart with demo content. Then I created a "VirtueMart >> Category Layout" Menu entry that pointed to the category "Wear" from the demo content. When following this link, I get redirected to

Assuming this is not a know issue, how could I dig this issue further ?
