unable to upload photos to a website
Hi there.
I have a macbook pro 2014 and am having difficulties uploading photos from the photo library to a website. I have done this in the past several times without any difficulty but currently it will not allow me to do so - I select the photo to upload and either get an error message or it opens a new tab to a black screen without the photo. I want to make a card for my baby son and firstly thought it was the website but despite trying several I simply cannot upload the photo or any photo. Frustrating to say the least. I am running OS Catalina which I updated recently and it is the only thing I can think of which is different since I last successfully made a photo card on a website. I am really grateful for any advice which may get me out of this frustrating dilemma. Thank you so much for any advice.
MacBook Pro 15″, macOS 10.15
