Following from my previous post, I managed to get rid of the fatal error message by deactivating the WD Backup plugin. Don't know why but the fatal error message has disappeared.

However now the issue is that the album does not load on the page. As I refresh it, a message appears instead of the images:
'There is no album selected or the album was deleted.'

I've redone it using the generate shortcode button and pasting it in the portfolio page but the same message above still comes up!

I would be grateful if anyone knows why this is happening?

Many thanks again,

Same problem. No ablum is displayed on my wordpress site. I get this message.
"There is no album selected or the album was deleted"

Hi, Greg!

Thanks for letting us know about this problem!

The newest update of Photo Gallery plugin has some issues and our development team is working to resolve them. In the meantime, we have rolled back to the previous version, where the issues are not present.

In case you have the free version of the plugin, please deactivate and delete current, then install the reversed version from WordPress.org.

But if you have Photo Gallery Pro, please again deactivate and delete, then go to WD Manager page, press Reload List and install The plugin. Please note, that you will not lose any data after deactivating and deleting.

Let us know if this helps.
Thanks! Have a wonderful day!
