This is because the class-json.php file has been removed from the official core files of WordPress (version 3.2). Solution: Copy from WordPress 3.1.4 /wp-includes the file class-json.php to /wp-includes version 3.2 and you will see that the plugin Tweetblender works again (it works for me). * [Peter Ould](https://wordpress.org/support/users/pould/) * (@pould) * [14 years, 10 months ago](https://wordpress.org/support/topic/class-json-error/#post-2165140) * I tried that Anja but it made no difference * [Anja Fokker](https://wordpress.org/support/users/afoka/) * (@afoka) * [14 years, 10 months ago](https://wordpress.org/support/topic/class-json-error/#post-2165141) * [@peter](https://wordpress.org/support/users/peter/) Ould: I only use the widget, see it on one of my testsites: [http://werkgroepen.net/wordpressmu/twentyten/](http://werkgroepen.net/wordpressmu/twentyten/) * [theworld365](https://wordpress.org/support/users/theworld365/) * (@theworld365) * [14 years, 10 months ago](https://wordpress.org/support/topic/class-json-error/#post-2165143) * Yeah, I tried placing class-json.php …/wp-includes and it still didn’t work. * When I tried activating the plugin I got the same error as before. Also, I’m using a set of 3 widgets and didn’t make any changes to posts, code, etc. Simply the widgets. * [theworld365](https://wordpress.org/support/users/theworld365/) * (@theworld365) * [14 years, 10 months ago](https://wordpress.org/support/topic/class-json-error/#post-2165144) * Is there a cache associated with this plugin… Maybe cleaning the cache would fix it after putting the old class-json.php in the includes dir. * I’m not using any caching plugins but other plugins have their own cache or tables that can be cleaned when issues like this happen. * Plugin Author [kirilln](https://wordpress.org/support/users/kirilln/) * (@kirilln) * [14 years, 10 months ago](https://wordpress.org/support/topic/class-json-error/#post-2165151) * [@peter](https://wordpress.org/support/users/peter/) Ould: Found the bug.
