Big problem with 404 error

 Hello

I have for some time a 404 error problem on most of the urls of the cLibre.eu site
I think I found it by disabling route66 for now and it works but with new urls :-(
I have the message:
) JROOT/libraries/src/Router/Router.php:153
2 Joomla\CMS\Router\Router->parse() JROOT/libraries/src/Application/CMSApplication.php:1069
3 Joomla\CMS\Application\CMSApplication->route() JROOT/libraries/src/Application/SiteApplication.php:820
4 Joomla\CMS\Application\SiteApplication->route() JROOT/libraries/src/Application/SiteApplication.php:228
5 Joomla\CMS\Application\SiteApplication->doExecute() JROOT/libraries/src/Application/CMSApplication.php:278
6 Joomla\CMS\Application\CMSApplication->execute() JROOT/includes/app.php:63
7 require_once()
Thanks for helping me, it's quite urgent because I'm going on vacation at the end of the week
Regards

Hi
It solved my problem/ too bad I didn't notice it before!
In any case, I also put a positive review (JED) on this extension and especially on your responsive support
Thanks
