How does the content item limitation work?
The Community and Small Business Editions come with limits on the number of content items that can be published. Once the limit is reached, you may create content only as a draft and will be able to publish it after another content item is unpublished. This limitation applies only to published items and does not restrict the total number of content items that can be created and saved in the system. Please, note that there is no limitation on blog items and images in the Community Edition.
