Unknown macro: 'calendar' - after the upgrade to 6.15.2

Hello all - 


We recently upgraded to confluence 6.15.2.  We are getting"Unknown macro: 'calendar'" errors. I tried to enable it, but it shows following errors in the logs:


Cannot resolve reference to bean 'bandanaToActiveObjectsMigrator' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'bandanaToActiveObjectsMigrator' defined in URL [bundle://254.0:0/META-INF/spring/spring-aomigration-components.xml]: Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: interface org.springframework.core.DecoratingProxy is not visible from class loader


I am also getting a "renew" button, but it takes me to licensing page. 


Can someone please help here?

Second, make sure that you have a valid license (commercial or evaluation to start with) of the app. Your screenshot suggests that it has expired. 

Third, if none of the above works, uninstall the app and install it afresh. Do not worry about the data as it will be preserved. But make sure that you try these steps in a non-prod environment first. 

I hope that helps!
