 * I recently activated the widget and when initially viewing my page it looks perfect,
   but once I click refresh or go to a different page my entire sidebar goes missing
   and is replaced with this message:
 * Fatal error: Call to undefined method DateTime::createFromFormat() in /home/content/
   00/10127100/html/wp-content/plugins/instagram-for-wordpress/wpinstagram.php on
   line 153
 * I have deactivated and reinstalled the widget several times only to experience
   the exact same issue.
 * Could you please help me resolve this issue?

 * Thank you!

 * Hello,
 * The widget uses the DateTime PHP library to determine if the cache has expired
   in the plugin.
 * It looks like your PHP installation doesn’t have this installed and so it isn’t
   working correctly.
 * Is there any chance you could contact your hosting provider to ask them if they
   could install the DateTime library for you?
 * We’ve had a couple of reports of this so we may go ahead modify the code to remove
   this dependency.
 * Many thanks,
 * Philip.

 * Hello,
 * Scrap my previous message, we’ve just pushed version 2.0.5 that removes the DateTime
   dependency from the plugin for you.
 * Could you please install version 2.0.5 for me and then let me know if this resolves
   the problem for you?
 * Many thanks,
 * Philip.

 * Hi!
 * WordPress didn’t notify of an update, so I uninstalled and reinstalled the plugin
   again, but I’m still getting the same error.
 * Maybe it takes some time for a plugin to go live? I’ll check back later this 
   afternoon.
 * Thanks!

 * Hello,
 * Apologies, I forgot to update the version number in the readme. You should be
   able to update to version 2.0.5 now.
 * Thanks,
