Preview mode seems to have stopped working (for all listings and new listings). Bascially nothing appears (Live mode and Editor mode work fine). GS is to up to date 7.0.15 (837) on OS 10.10.5, and ebay token refreshed.
In the console I get this message when clicking preview:
24/06/2018 09:22:52.859 GarageSale: GSPreviewGenerator: Received exception while running MiscMerge -[NSCache setObject:forKey:cost:]: attempt to insert nil value (key: com.myserver.2017-design)
Any help greatly appreciated
