I’ve been using EventCalendar3 for a couple of years. It’s a great plugin and version 3.1.4 still plays nice with WordPress 2.9.x. However, I was rolling out a new website with WordPress as CMS with a requirement for a Big Calendar. A couple of EC3 users had built big calendar capability into the development branch. The last beta version (EC3.2 beta 2) had big calendar functionality built in so I installed it. After I made the move to WordPress 2.9, everything seemed to be working fine until I realized my comments feed was returning a 404 all of a sudden. Comments on posts were feeding properly as were category based feeds and the site feed. So, I went through all the usual troubleshooting (check the wordpress.org forums and deactivate plugins). Turns out EC3.2 beta 2 was the culprit. When I deactivated it, my comments feed started working again.
I’ve spent a fair share of time going through the EC3 code over the past couple of years and couldn’t figure out what EC3 and comments had to do with each other. EC3 does highjack some feeds and futz with canonical redirects but everything I saw in the code seemed benign. I commented out some of the redirect functions with no luck. On my other blog with E3.1.4, my comments feed was fine and the plugin is still solid despite its apparent abandonment. Odd. After a couple of hours of troubleshooting, I packed it in.
Fortunately, I hit gold on my first stop through the WordPress plugin repository with Kieran’s excellent calendar plugin. It’s a no nonsense big calendar with two useful template tags to generate lists of events. While similar to EC3 in that it uses a separate table to store event data, it differs in that you add the events using a backend form rather than the posting method EC3 uses. You can link the event on the calendar to a blog posting (or any other url) which is a nice touch as well. Kieran’s plugin also seems pretty bulletproof as WordPress evolves.
It’s sad when a plugin withers away but plugin authors are very special people who give without compensation (for the most part) and are swamped with support requests from all kinds of folks who should have RTFM. When or if EC3.1.4 finally breaks, there’s an alternative.
