A bit of bad news, but a lot of good news when it comes to Twitter.
As you know, widgets are only as good as the developer that updates it and one of our widgets “Latest Twitter Sidebar Widget” is no longer functioning and the developer will not be updating the plug-in due to Twitter’s new API. I will be removing it from the list of available plug-ins.
Onto the good news!! We were using that widget because at the time when I installed it, WordPress did not offer a way to show your feed from the dashboard. Jetpack, in one of its later releases, did just that and you will find in the Jetpack menu the following option for Extra Sidebar Widgets
With this widget you can add:
The RSS Links Widget lets you easily add post and comment RSS feeds to a sidebar on your theme.
The Twitter Widget shows your latest tweets within a sidebar on your theme.
The Facebook Like Box Widget shows your Facebook Like Box within a sidebar on your theme.
The Image Widget lets you easily add images to a sidebar on your theme.
Each of these widgets has a number of customization options. To use the widgets, go to Appearance → Widgets. Drag them into one of your sidebars and configure away.
As always, feel free to contact me if you need any help.
