Yes this applies to all our products. So they will be released very soon.
Thanks for your kind words.
It looks like you are using an older version of the SevenSpikes.Core plugin. Would it be possible to update both plugins SevenSpikes.Core and SevenSpikes.Theme.Pavilion to their latest versions by downloading them from your My Downloads section and replace your plugins with the newly downloaded. After that just restart the application from your administration and the issue should go away.
Note: always update the SevenSpikes.Core plugin when you update any other SevenSpikes.* plugin.
Thank you for your feedback. The issue occurs because the Nop Ajax Cart plugin is disabled. We will fix that and will let you know once it is ready.
In the meantime you can enable the Nop Ajax Cart plugin which will fix the issue and the Details button will be displayed where it should be.
