Hi guys.
A few days ago my forum started having a problem with the images that have been uploaded. When clicked, the images open but get stuck, no way to close them. They are also very blurry as you can see in the pic I attached.
I don’t know exactly when it started, but I think since the last upgrade. Before, it was working perfectly.
I thought it could be a conflict, so I switched off every single plugin. Nothing changed.
Is there a way to fix the problem?
Thank you!
