Just installed really-simple-twitter-feed-widget (after installing "really-simple-facebook-twitter-share-buttons"). I added the widget to my "header" widget space, and the tweets showed up nicely.
I them moved the widget to my sidebar widget, and now I get a Fatal Error.
Moving the widget back to the header doesn't help. I did not change any setting in between, so am a bit puzzled ; )
While I am writing this and doublechecking everything I am writing her, I noticed that line 62 in th ementioned file reads:
' $max_items_retrieved = $rss->get_item_quantity(); '
I had set the value for 'Show # of Tweets' to 5. But since I use a test account, I have only 3 tweets in that account. So I set the value to "2", but that didn't help.
I use the Custom Community 1.8.3 by Themekraft theme.
