Running latest version of RW 8.1, latest version of Stacks, all stacks updated.

“Unable to load CMS preview libraries. Try adding a CMS Text stack to the bottom of your page.”

I have no idea how I turned this on or what I added.

I updated to RW 8.1, updated to latest stacks, updated one stack from JW I think (can’t figure out which)

Shows up in preview in every theme at top of page.

What am I not seeing?

Remember, this is a BETA version of RapidWeaver. I would send in your project file to Dan as he suggests in this thread:

> Hello Weavers, This is the first public beta for RapidWeaver 8.1 — in this version we’re focusing on stability, improving export/preview speeds, and making sure we’re compatible with Mojave when it launches (expect to see dark mode support in a future beta). So with that out of the way, here’s a list of what’s new: Fixed an issue where RapidWeaver would re-publish all files on every publish Fixed an issue where RapidWeaver would get stuck looping between pages Fixed an issue where the incorr…

More info, I feel like I’m a real detective:

Duplicated project file, deleted stack, tested, problem no longer present — must tie to the stack right?

It shows in edit and preview mode. Also shows in Preview in Firefox. Also in Simulate and Menu - View; Menu Item - Preview Page.

Wish I would have done a better job bug tracking yesterday, probably would have known to go rightly to Joe site to report problem rather than RW forums.

I’m an idiot – I had the Danger Zone box checked so this is Version 8.1 (20217b)

Had no idea of the ‘Send to Dan’ protocols, will now figure those out and comply.
