After a while, I opened Rapidweaver to start building new project and then there was update offered, so I clicked update. After update, I have 7.1.7 abd the problem is, I can’t use Stacks anymore. All my old projects report error missing plugin Stacks. I reinstalled Stacks and it just doesn’t help.
I will look into this further now, on my second mac in order to see if it works there.
If you are going to use the beta of Stacks, I would also suggest you join the Yourhead Slack channel http://slack.yourhead.com/
as this is the place to report bugs and issues with any of Yourhead’s software. Slack is a free app too.
