I just uploaded version 1.2.2 of my WordPress Twitter Widget Pro plugin. Since twitter has slowed down, a lot of people (especially on slower servers) have been getting the “Could not connect to Twitter” message when twitter was slow but not down. I’ve added a setting on each widget to specify the number of seconds to wait for Twitter. It still defaults to 2 seconds, but you may have to bump it up. Just remember that when twitter IS down, it will try for that full amount of time to reach them BEFORE your page loads, so don’t set it too high!
Please discuss this plugin on the WordPress Twitter Widget post.
