Title: Javascript error Last modified: August 30, 2016 --- # Javascript error * Resolved [grizgza](https://wordpress.org/support/users/grizgza/) * (@grizgza) * [10 years, 6 months ago](https://wordpress.org/support/topic/javascript-error-91/) * When I attempt to run Create Photos, nothing happens. I checked the console and saw some errors. * The following error shows immediately when I load the settings page: * Uncaught TypeError: Cannot read property ‘length’ of undefined jquery-1.7.2. min.js:2 * This error appears when I attempt to Create Photos: POST [http://10.1.10.8/wp-content/plugins/active-directory-thumbnails/php/pic-process.php?user_id=1570](http://10.1.10.8/wp-content/plugins/active-directory-thumbnails/php/pic-process.php?user_id=1570) 500 (Internal Server Error) jquery-1.7.2.min.js:4 * Any idea what might be going on? * [https://wordpress.org/plugins/active-directory-thumbnails/](https://wordpress.org/plugins/active-directory-thumbnails/) Viewing 6 replies - 1 through 6 (of 6 total) * Plugin Author [Omar Mir](https://wordpress.org/support/users/mirwindsor-omar/) * (@mirwindsor-omar) * [10 years, 6 months ago](https://wordpress.org/support/topic/javascript-error-91/#post-6747493) * Well, I found a few issues that could cause it but I have been working on a new version that would avoid a lot of those issues. * Can you try using the development version? It should be published soon and is pretty stable, I’m just trying to add another feature before I release it. * Please make sure to deactivate and delete the current plugin. I’ll post back here when the plugin is published. * [https://wordpress.org/plugins/active-directory-thumbnails/developers/](https://wordpress.org/plugins/active-directory-thumbnails/developers/) Download the “Development Version” under other versions. * Plugin Author [Omar Mir](https://wordpress.org/support/users/mirwindsor-omar/) * (@mirwindsor-omar) * [10 years, 6 months ago](https://wordpress.org/support/topic/javascript-error-91/#post-6747509) * Actually just put up a RC you can download it here: [https://downloads.wordpress.org/plugin/active-directory-thumbnails.1.03rc1.zip](https://downloads.wordpress.org/plugin/active-directory-thumbnails.1.03rc1.zip) * Or * [https://wordpress.org/plugins/active-directory-thumbnails/developers/](https://wordpress.org/plugins/active-directory-thumbnails/developers/) Download the “1.03rc1” under other versions. * Let me know if that works OK 🙂 * Thread Starter [grizgza](https://wordpress.org/support/users/grizgza/) * (@grizgza) * [10 years, 6 months ago](https://wordpress.org/support/topic/javascript-error-91/#post-6747629) * Thanks for your help. * Now I’m getting this error on 1.03rc1: * [http://10.1.10.8/?active_directory_thumbnails&nonce=4268ad786d](http://10.1.10.8/?active_directory_thumbnails&nonce=4268ad786d) Failed to load resource: the server responded with a status of 500 (Internal Server Error) * Plugin Author [Omar Mir](https://wordpress.org/support/users/mirwindsor-omar/) * (@mirwindsor-omar) * [10 years, 6 months ago](https://wordpress.org/support/topic/javascript-error-91/#post-6747630) * The only thing I can think of is permissions. After activating the plugin is there a folder inside the uploads directory called active-directory-thumbnails? * Also do you have php installed with GD? PHP requires an image manipulation library for this to work. To check see here for instructions: [http://www.zoopable.com/check-php-gd-library-installed-or-not/](http://www.zoopable.com/check-php-gd-library-installed-or-not/) * A server error 500 would imply something wrong on the server. * Thread Starter [grizgza](https://wordpress.org/support/users/grizgza/) * (@grizgza) * [10 years, 6 months ago](https://wordpress.org/support/topic/javascript-error-91/#post-6747644) * I did not have PHP GD installed. Installed it and now your plugin works!
