Blank grey rectangles in Woo dashboard

Hi,

I’m having a few issues with a newly installed Woocommerce ..

In the WP dashboard, if I click on anything Woocommerce related from the menu (whether that’s the overall WooCommerce menu entry, the payments page, Reports, or anything else Woo related) the page just displayed lots of blank grey rectangles.

After searching the forum it seems quite similar to this issue from one year ago:

If I click around and refresh the page a few times I also (occasionally) get the “There was an error getting your inbox.” error message too. (similar to this issue from three years ago: https://www.ads-software.com/support/topic/error-there-was-an-error-getting-your-inbox/. )

The only non-Woo plugins I have installed are Change wp-admin login and Contact Form 7. I disabled both of these, logged out, cleared my cahce, logged back in… and the above issues persisted.

I’m using the default Twenty Twenty Four theme.

Another thing I’ve noticed is that any Woo related page in the dashboard takes ages to load. Any other link in the dashboard menu is fairly quick, but clicking on any Woo related thing in the dashboard menu takes serveral seconds to load, before displaying just blank grey squares.

The really odd thing is… If I then minimise the browser and then maximise it again, the blank grey squares are gone and I can read the info on the page. But even this is not consistant.
