I can’t get past the Age Gate / The Age Gate only worked once
Can I restrict a particular page?
You can. If you use selected content, a checkbox will appear in content pages
Can I add my own logo/branding?
Of course, it's your site
I’m in X country, can I format the date style?
Yes! DD MM YYYY and MM DD YYYY are supported along with a choice of how the dates are entered.
I use caching, will that be affected?
From version 1.4.0 those using caching can select the "Cache Bypass" option to allow age gating even with caching on. Be sure to empty your cache when making changes to the plugin settings. From 2.0.0 this option is in Advanced -> Use uncachable version
