CMS Collection says "This Collection does not contain any items" but it was working fine yesterday

As the title suggests, I’m building a portfolio site and suddenly the CMS Collection gives me that error message. What disturbs me is that it is working fine on other PC and tablet! So I’m assuming there must be some kind of problem with my cache or local data, but I have no clue where to start looking.

I’m attaching an image of what I’m currently experiencing. This error is consistent through Google Chrome, Firefox and Opera, and it also happens on incognito mode. However, as I said before, the list works perfectly when I open my project on a different PC. Problem is, I need to work on mine!

I would appreciate any suggestions regarding what the nature of this error might be. Best regards!

Click on settings and your collection list, and make sure you do not have “Empty state” selected for your collection list view.
