P: Quick Export not working

I have had this issue and now have a work around. All you have to do is create a new document in Photoshop and drag the layers or even the whole artboard to the new document. Boom. You can export now.

Hope this works for you. Not a fix but better than nothing.

I was only able to get it working again by reinstalling. Did that about a week ago, and haven't had any issues since.

You need to update to latest update. It was fixed (at least I haven't the issue since I updated).

Which version do you have?

This just stopped working for me recently. 

I just re-installed Google Nik Efex, and copied the others over from the Photoshop 2015 folder to the Photoshop 2015.5 plug ins folder.

They seem to work...:)

Great, thanks for confirming it's working for you.  Your plug-ins should still be in your Photoshop CC 2015 directory.

No, I'm saying it started working before yesterday, and I just checked, and it's still working now. 🙂

I don't have my plug-ins anymore though (Portraiture, Google Nik Efex, and Topaz though... I can't find where/ how to add those... 😞 )

Thyago, is Quick Export not working at all?  Also, are you accessing it via
1) File > Export > Quick Export as (type),
2) right-click on layer in Layers panel > Quick Export as (type), or
3) Layers panel flyout menu > Quick Export as PNG (there is a bug where the type doesn't update in this instance when it's changed via preferences, but the actually export type is correct).

Craig, are you saying it's not working now since you updated yesterday?
