Please use the following information to try to resolve the problem. * Error Code: `php_code_error:64:/home/dioni2a/public_html/ceorandy/wp-content/ plugins/wp-dtree-30/uninstall.php:5:require_once() [function.require]: Failed opening required 'wp-dtree_cache.php' (include_path='.:/usr/lib/php:/usr/local/ lib/php')` Message: A fatal code error occurred. * If you are unable to fix this problem, please copy all the text on this screen and send it to [support@ithemes.com](https://wordpress.org/support/topic/plugin-wp-dtree-function-require-fatal-error-during-uninstall/support@ithemes.com?output_format=md). * Debug Data: * ``` Array ( [0] => Array ( [file] => /home/dioni2a/public_html/ceorandy/wp-content/themes/Builder/lib/classes/it-error.php [line] => 121 [function] => fatal [class] => ITError [type] => :: [args] => Array ( [0] => php_code_error:64:/home/dioni2a/public_html/ceorandy/wp-content/plugins/wp-dtree-30/uninstall.php:5:require_once() [function.require]: Failed opening required 'wp-dtree_cache.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') [1] => A fatal code error occurred. ) ) [1] => Array ( [file] => /home/dioni2a/public_html/ceorandy/wp-content/themes/Builder/lib/classes/it-error.php [line] => 148 [function] => handle_error [class] => ITError [type] => :: [args] => Array ( [0] => 64 [1] => require_once() [function.require]: Failed opening required 'wp-dtree_cache.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') [2] => /home/dioni2a/public_html/ceorandy/wp-content/plugins/wp-dtree-30/uninstall.php [3] => 5 ) ) [2] => Array ( [function] => it_error_shutdown [args] => Array ( ) ) ) ``` * — * I have some familiarity with html and css but am still pretty inexperienced with php. Is there an easy fix here? * Thanks for your help.

I Forgot to test the uninstallation procedure after the rewrite. Commited the fix just now – you’ll get an upgrade-notice through the wordpress admin panel, or you can download 4.2 from the repo within 15 minutes. * Thread Starter [diongeborde](https://wordpress.org/support/users/diongeborde/) * (@diongeborde) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-wp-dtree-function-require-fatal-error-during-uninstall/#post-1744378) * Wow Ulf! * What an incredibly fast response. Thanks so much! I’m now actually reconsidering keeping it, but I do have a question if you don’t mind: How do I modify or delete the dashed lines and expansion boxes? * I think I’d want to keep this great plugin if I could just make it a list without any graphic component, where the site visitor simply clicks on top-level headings to open the lower level links. * Could you explain that please, or direct me to where I might find how to do that? I’m comfortable with CSS. I just haven’t found the settings to adjust these elements. * Thanks again! * Plugin Author [ulfben](https://wordpress.org/support/users/ulfben/) * (@ulfben) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-wp-dtree-function-require-fatal-error-during-uninstall/#post-1744425) * “Use lines” is a setting available directly in the widget. For the plus-sign you’d have to open the dtree javascript – right at the top are all the declarations for the graphical elements. Pick out the filename of the plus-sign and search for it in the file. Edit as necessary to not have them output at all. * Note though that WP-dTree uses the minified JS-file, not the “clear text” one. So once you’ve made your edits to the plain-text, rename the file so it’s the same name as the minified version of the script. * … or you could tote together a CSS-selector and just hide the gif or something( display:none;). Use the Chrome-browser, and right click any element to bring out all it’s properties and applied styles, you can edit it live to see what works and then apply those adjustments to your stylesheet.
