The Foundry V1 and V2 theme is compatible with Stack V5? or do we need to purchase another version of stack? If yes can you please mention which version i need to buy which is compatible with Foundry V1 and V2.
Foundry is comprised of both a theme and Stacks-based addons. The Stacks based addons for Foundry v1, v2 and v3 will definitely work with Stacks v5.
Other people from your organization, or I assume they’re from your group since they share domain names in their email addresses, have posted on this topic. You will need to rebuild the site using Foundry 3, as Foundry versions prior to v3 are no longer available to purchase.
