Inaccessible statistics button

[santilococo]

Describe the bug
Currently, there is a bug on the website that prevents users from selecting the statistics button. This issue is likely due to a permissions problem with the API, as it resulted in a 403 error at one point.

To Reproduce
Steps to reproduce the behavior:

1. Open the website while being logged out. Before opening the website, it is recommended to clear the browser cache. For example, open the demo.
2. Upon opening the website, you will notice that the statistics button is disabled, and you are unable to click on it.
3. Reloading the page on ${DSPACE_URL}/home will not resolve the issue. However, if you navigate to ${DSPACE_URL}/community-list or ${DSPACE_URL}/statistics and then reload the page, the statistics list will load, and you will be able to click on the statistics button.

Expected behavior
The statistics lists should always be clickable. At least with the site option.
