Hi @alexander!
After installing the Beta 4, I am getting a critical error. Tested with or without the Child theme.
Summary
**Fatal error** : Uncaught ArgumentCountError: Too few arguments to function Cornerstone_Condition_Rules::expression_datetime_before(), 1 passed and exactly 2 expected in /home/customer/www/***/public_html/wp-content/themes/pro/cornerstone/includes/_classes/class-condition-rules.php:420 Stack trace: #0 [internal function]: Cornerstone_Condition_Rules::expression_datetime_before('') #1 /home/customer/www/***/public_html/wp-content/themes/pro/cornerstone/includes/classes/Services/RuleMatching.php(56): call_user_func_array(Array, Array) #2 /home/customer/www/***/public_html/wp-content/themes/pro/cornerstone/includes/classes/Services/RuleMatching.php(65): Themeco\Cornerstone\Services\RuleMatching->evaluate(Array) #3 /home/customer/www/***/public_html/wp-content/themes/pro/cornerstone/includes/classes/Services/RuleMatching.php(80): Themeco\Cornerstone\Services\RuleMatching->matchRuleGroup(Array) #4 /home/customer/www/staging7.optika-kobacic. in **/home/customer/www/***/public_html/wp-content/themes/pro/cornerstone/includes/_classes/class-condition-rules.php** on line **420**
