What version of WordPress are you running? Unless your WP is pretty out of date, the problem must be with your theme. Try turning off all your other plugins and switching to one of the default themes (twenty ten or twenty eleven).
I am having the same problem. I use the Yoko theme. Installed the widget, activated it, configured it, but it does not show on the “available widgets” page. Running WP 3.3.1.
Oops! Got it! It appeared after I deactivated my former twitter widget plugin, which had broken. Thanks for the plugin!
Well, 3.3.1 is out of date but I just set up a test install of 3.3.1 and added/activated Twitter Widget Pro. The widget showed up as expected. I even switched to the Yoko theme and it still shows correctly: http://cl.ly/image/1o2t1a3u2O1p
Are you sure you’ve disabled ALL other plugins?
Yah, like I said above, it worked after I deactivated my old, bad twitter widget plugin. Thanks again!
I’m running 3.4.2. Unfortunately it appears to be the theme that’s the problem. Having spent too long getting the theme looking just how I want it to, I think I’m going to stick with it.
Is it a publicly available theme? It’s likely a small error somewhere (and will probably affect other widgets too).
The theme, Besta, was downloaded from Magpress. It already had a twitter widget built in however this stopped working in the last few days.
That means your theme isn’t registering it’s widget when it’s supposed to. There used to be a similar problem with the Twitter Widget in Jetpack, but TWP now unregisters any conflicting widget just before it registers itself. Since widgets should register themselves on the widgets_init hook at priority 10, I do all this on the same hook at priority 11. Your theme is either registering on the wrong hook or on a priority higher than 11.
Look in your theme for a call to register_widget() and comment it out. That should probably fix things for you.
Having this problem too. On WP 3.5.1 and using the ‘Headlines’ theme 2.4.1, framework 2.6.5. Any idea where I would find ‘register_widget()’ to comment it out?
Thanks
