I have this same issue and it has been highlighted in a previous thread but didn’t get resolved. Not related to Foundation as I am using Foundry. Not sure if it is a Stacks issue or RW issue. > [@Preview Error in RW 8.1.5 and 8.1.6](http://forums.realmacsoftware.com/t/preview-error-in-rw-8-1-5-and-8-1-6/25489): > > Since upgrading to 8.1.5, I have been receiving an error message when previewing Stacks pages. This error message is not the same as error messages I have seen documented created using the ThemeFlood Blank theme and GoCMS. The error I received is as follows: Fatal error : require\_once(): Failed opening required ‘/private/var/folders/9p/c9h83wl08xj\_\_r0059b3v95r0000gn/T/com.realmacsoftware.rapidweaver8/RapidWeaver/43280/document-0x7f8374f933a0/RWDocumentPagePreview/rw\_common/plugins/stacks/cmsgo… Close and reopen the project and we’re good to go again for a while. Sometimes it happens frequently other times not so much. I’ve learned to live with it however a fix would be nice. --- _[View the full topic](https://forums.realmacsoftware.com/t/fatal-error-when-returning-to-home-in-preview/29031)._
