It’s possible to search for blog posts on the Elytron website using tag names. The tags appear on the right hand side of the blogs page.

There are currently a couple of invalid tags that end in a comma: “certificate,” and “ux,”. Clicking on these leads to a 404. The tags associated with a post appear in a tags line in the post and should be separated by spaces. An example of a post with valid tags can be seen here.

For this task, you’ll need to search for "certificate," and "ux," in the *.adoc files in the _posts directory to find post(s) that are incorrectly using a "," for the tag delimiter and remove the commas.

The source code for the blogs page can be found in the develop branch of the wildfly-elytron repo:
