# Plugin causing problems since upgrade to 3.9

 * Also upgraded to new version of W3 Total Cache.
 * Over next 24 hours, the plugin only intermittently showed tweets, and my site
   went down entirely in the late afternoon. According to my host (I don’t have 
   access to error logs), they were seeing this error:
 * PHP Warning: Invalid argument supplied for foreach() in /var/www/sitename.com/
   wordpress/wp-content/plugins/really-simple-twitter-feed-widget/really_simple_twitter_widget.
   php on line 448

 * Hi, thanks for noticing it. The new 2.5.1 plugin release is out now, fixing that
   issue. Cheers!

 * Thanks. I upgraded, now the widget just says “No public tweets”.

 * Oops…after a bit more investigating, looks like users that are logged in, so 
   seeing un-cached content, see “no public tweets”. Users that are not logged in,
   so seeing cached content, see a blank space.

 * What do you see when the plugin “Erase cached data” option is enabled?

 * That makes it function properly. I assume it has a performance cost though?
 * And huge thanks for the quick help!

 * Leaving the “Erase cached data” enabled for long time can cause empty data from
   Twitter, because the Twitter API is rate limited: you have a fixed maximum amount
   of requests every 15 minutes. Hopefully your “W3 Total Cache” should limit the
   widget renderings and the Twitter API calls, so it could work for your website.
 * Anyway, if you enable “Erase cached data” for some minutes and then you disable
   it, the WordPress cache gets refreshed; it’s a quick way to empty the cache and
   solve temporary issues like the “no public tweets” string.

 * It didn’t work for long, I am back to “no public tweets”. So the only way I can
   get this to work is to enable & disable “erased cached data” on some regular 
   basis?

 * The plugin works fine on thousands sites, but in some website with different 
   plugins active together it suffers data loss. I’m studying an easier solution
   for these api+transient+cache issues … I’ll let you know when I find something
   useful!
