changing https to http worked for me too.
but it wasn’t line 186 but line 904 on wp-twitter-widget.php
simple method:
* just go to your list of installed plugins
* under ‘twitter widget pro’ select ‘edit’
* in the opened page, go to the very bottom of the code
* find ‘http_vs_https’ => ‘http’, (line 904 on editors)
* save and refresh
hope that helped others.
thanks Ryan 🙂
I had the same problem. One thing I figured out is the plugin causing it which is SFC (simple facebook connect). Having both active at the same time causes trouble. I don’t know how to overcome this problem though and I’d appreciate anybody who can share the fix 🙂
