Since December 21 - which may have been when I upgraded to v3.1.5 - I have lost some functionality in my Media upload window and when trying to use the Edit Media function. These issues persist with all plugins deactivated - and even after upgrading this morning to v3.1.6 (for which, merci beaucoup, @Nikeo). I'm using the latest version of WP and running offline in a MAMP environment.
Here's a screen grab of my Media library window, showing that the preview images stopped displaying on Dec 21.
And here's a screen grab of the Edit Media window - which wrongly states that the media doesn't exist.
Also missing from both windows are the image dimensions (which are still correctly shown for all images uploaded before December 21).
Notwithstanding this inconvenience, I am still able to place newly uploaded images on my pages and sliders and they display correctly when I preview the pages in my browser.
The only CustomizIt Images Option I have enabled is Enable/disable lightbox effect on images.
Is this a known bug? I would be grateful to know if there is a cure. TIA.
