Download and Categorie features not working properly

Hi,

We are trying to migrate to Joomla 4 from 3.10 using EDocman 1.23.3.
Almost all plugins work fine but we are having some issues wit EDocman.

1.when either trying to download a document, it does not work. when I look in the network tab i can see a 404 when downloading a document, i however i can view the document. here are some screenshots
2. when trying to view a category in a new tab it just goes to the home page, even though the links look fine, some screenshots

How could we fix these issues?
thanks in advance.

Hi Rob,
With this kind of issue, you can submit ticket on category: Edocman and provide your site url with super admin account. I will figure the problems for you
Thanks
