Follow the steps below to quickly get Solspace Calendar setup in minutes.

  1. Customize and configure Solspace Calendar settings by visiting the Settings page (Freeform > Settings).

Common Issues

Currently, there are only 2 known issues:

  • ISSUE: After installation, when going to Calendar page I am getting the following error: "Method "settings" for object "Craft\CalendarVariable" does not exist"
    • CAUSE: If you have the Tipping Media Venti plugin currently installed, you might run into this issue due to a namespace collision. Calendar uses the Calendar namespace, but Venti seems to sometimes use it as well.
    • SOLUTION: If your site is not live, or you're not dependent on this plugin, simply disable it (Settings > Plugins then click Disable button) or if you're not using it, uninstall it.
  • ISSUE: When attempting to use Calendar on front end templates, I am getting the following error: "Call to undefined method CalendarLibraryCarbon::setWeekStartsAt()"
    • CAUSE: The issue has to do with another third party plugin installed that also uses Carbon. A commonly reported plgin is Postmaster, which appears to be using an older copy of Carbon. Calendar ends up loading Postmaster's Carbon library, causing this issue.
    • SOLUTION: Manually updating the vendors directory for the affected plugin to use latest versions may resolve this issue. Customers affected with this issue specifically for Postmaster plugin can contact Solspace support for an updated vendors folder for Postmaster that may resolve the issue.
