Hi I’m new to PHP and am in a ‘pickle’ as I need to get this Twitter widget working and the theme developer hasn’t responded to my emails. My client is getting aggravated and I need it fixed.
I hope one of you kind people could help me.
After I have set up the tokens keys etc to the Twitter widget…it will operate temporarily. However, after a while (last time was possibly an hour) an error will appear:
Warning: Invalid argument supplied for foreach() in /home/…/framework/inc/widgets/twitter/widget.php on line 157
If you any of you brave souls attempt to fix this for me THANK YOU SO MUCH IN ADVANCE!
The code for this as follows (and line 157 is blank):
<?php /* Plugin Name: Recent Tweets Widget Plugin URI: http://wordpress.org/extend/plugins/recent-tweets-widget/ Description: Recent Tweets Widget plugin for Twitter API v1.1 with Cache. It uses the new Twitter API v1.1 and stores tweets in the cache. It means that it will read status messages from your database and it doesn't query Twitter.com for every page load so you won't be rate limited. You can set how often you want to update the cache.
