After allowing my users to vote among six different three-column themes for my blog, “Emerald Stretch” was the winner.
Unfortunately, only after using it for 10 months did I discover a latent bug: links to "Subject" categories results in a Parse Error due to a coding error. As a result, users can't get a list of posts on a particular topic.
I looked at the page in question producing the error, but could not find the faulty code to try and fix myself.
The author seems to have stopped supporting this theme so it is unlikely the bug will ever be fixed. Pity.
