The Access settings for Post forms are configured at Toolset > Access Control > Toolset Forms, by expanding the section for front-end Post forms.
That section is currently broken. The checkboxes don’t respond to clicks, and horizontal scrolling to see settings that don’t fit the page does not work.
It appears this is also affecting other Access settings pages, such as setting permissions for post types.
This is now fixed. You may need to use the Check for Updates button on the installer page to see the update notice, or download the latest versions from toolset.com/account/downloads
