Hi
Could you please set full error reporting.  In System go to Global Configuration. On the System tab set Debug System to Yes.
Then on the Server tab set Error Reporting to Maximum

In the backend I can't view the list of categories (administrator/index.php?option=com_jdownloads&view=categories) and the error appears
0 implode(): Argument #2 ($array) must be of type ?array, string given

in the front-end if I want to see the contents of the single file within a subcategory it gives me an error:

500 - Unknown column 'c2.id' in 'field list'

Hi
1.Which version of jD did you install?

2. Did you remember to create a jD menu item 'All Categories'? It can be a 'hidden' menu item

3. Also Please set the error reporting as advised earlier as that gives much more information . After copying the error report (NOT an image) into a post here you can revert it to normal.

4. it may be because of using PHP8 - I am setting up a test site on XAMPP
