Presumably, there is an issue with the addins of social networks after the recent WP updates have been introduced (I might be wrong about the updates as the cause). As a result:
– Twitter widget (Jatpack widget) is no longer working;
– I use iframe to add Facebook timeline to my page – that is no longer working;
– Regarding the Sharing Settings: the official buttons are not working and I have to use the Icon+Text option.
I run three WP blogs and am experiencing these problems on all of them.
If you visited my blog, you would see a broken link “My Tweets” on the right side instead of the fully working Twitter widget. The Facebook timeline should appear under the Twitter’s widget but it is also missing.
