"Cannot complete this action" error when you click a category tile inside a community for a SharePoint Online site


Consider the following scenario:

  • In Microsoft SharePoint Online, you save a subsite as a template by selecting the Save site as template option in Site Settings.

  • The template was saved from a site that uses either a Team Site template for which the Community Site Feature is active or a Community Site template.

  • You use the template that you saved to create a subsite.

  • You create a category in the community and then click the tile for the category.

In this scenario, you receive the following error message:

Cannot complete this action. Please try again.


To work around this issue, create sites from a standard SharePoint Online template when you plan to use community categories. Categories will function correctly on a site that wasn't created from a site saved as a template.
