 * Hi
 * I get this error on my production environment (Not yet live)
 * Fatal error: Uncaught exception ‘RuntimeException’ with message ‘Unimplemented’
   in /inc/plugins/twitterfeed/app/Widgets/Widget.php:111 Stack trace:

 * But On my localhost i works like a charm. I do however have iThemes Security 
   plugin installed and have changed the wp-content folder to inc.. I dont know 
   if this could be the reason??
 * Hope you can help as soon as possible 🙂
 * Thanx in advance.

 * I tried deleting the wordpress and DB installation, and did a complete fresh 
   install.
    I then installed the Twitterfeed plugin:
 * Error still shows?
 * Are there any special server requirements for this plugin.

 * OK I’ve come so far as to track the problem to Widget.php.
 * ‘
    “name” => static::get_name(), “version” => \TwitterFeed\PLUGIN_VERSION, “languages-
   ur” => \TwitterFeed\PLUGIN_DIR . “languages/”, “description” => “Use this widget
   to display tweets in your widget area”, “callback” => function( $args, $instance){`…//
   Render the tweets static::render( $instance ); … },… ` The static::get_name()
   outside the callback gets the correct function inside StaticTweets.php
 * But static::render() inside the callback function is not getting the render function()
   from extended class StaticTweets.php but from the Abstract class Widgets??
 * Why this is happing on my host provider and not on my localhost I have no idea..
   
   Hope You can help with this one as its causing grey hairs 🙂

 * This exact thing is happening and has been for a few versions on my local VVV
   install on SiteGround and on WP Engine. I have tried it with a fresh install 
   as well.

 * We only use the static tweets so i solved it by doing the following in Widgets.
   php:
 *     ```
       // Render the tweets
       //static::render( $instance );
       StaticTweets::render( $instance );
       ```
   
 * Its not pretty but it works for now.

 * Hi yearhouse,
    thank you for hunting down the root of the issue. However, your
   solution will only work if you using `StaticTweets` by itself. The `static::`
   keyword is used for late static binding, which is needed in this case.
 * It is very strange that `StaticTweets::render( $instance );` worked for you, 
   while `static::render( $instance );` didn’t. It should have been the other way
   around.
 * What PHP version are you using?

 * The new version (2.1.4) should resolve your issue.
