Title: PHP Fatal error: require(): Failed opening required… Last modified: August 22, 2016 --- # PHP Fatal error: require(): Failed opening required… * [sideways](https://wordpress.org/support/users/sideways/) * (@sideways) * [11 years, 4 months ago](https://wordpress.org/support/topic/php-fatal-error-require-failed-opening-required/) * I updated the plugin to newest version and the site went to white page of death( both front and back). * I followed this: [https://wordpress.org/support/topic/white-screen-or-blank-page-with-all-in-one-event-calendar-please-read-1?replies=17](https://wordpress.org/support/topic/white-screen-or-blank-page-with-all-in-one-event-calendar-please-read-1?replies=17) * 1. I checked the error log and it gives me these 2 errors: * PHP Fatal error: Call to a member function get_all_items_name() on a non-object in /web/htdocs/www.firenzekids.it/home/wp-content/themes/made/functions.php on line 74 * AH01215: PHP Fatal error: require(): Failed opening required ‘/web/htdocs/www. firenzekids.it/home/wp-content/plugins/all-in-one-event-calendar/lib/http/response/ helper.php’ (include_path=’.:/php5.3/lib/php/’) in /web/htdocs/www.firenzekids. it/home/wp-content/plugins/all-in-one-event-calendar/all-in-one-event-calendar. php on line 41 * 2. I tried many tricks around but none solved my issue. I also tried to downgrade but I wasn’t able to actually reinstall the plugin. * 3. Did it, but it didn’t work. * 4. Here I am. * I’ve renamed the folder to bring back the site to life. * Help! * [https://wordpress.org/plugins/all-in-one-event-calendar/](https://wordpress.org/plugins/all-in-one-event-calendar/) Viewing 7 replies - 1 through 7 (of 7 total) * [Nicola Peluchetti](https://wordpress.org/support/users/nicolapeluchetti/) * (@nicolapeluchetti) * [11 years, 4 months ago](https://wordpress.org/support/topic/php-fatal-error-require-failed-opening-required/#post-5679145) * Hi, can you try to delete the whole folder, re download the plugin and copy it over with ftp? * Thread Starter [sideways](https://wordpress.org/support/users/sideways/) * (@sideways) * [11 years, 4 months ago](https://wordpress.org/support/topic/php-fatal-error-require-failed-opening-required/#post-5679188) * That’s what I did.

We can’t do much for the Theme, but for our plugin, it seems that `/web/htdocs/www.firenzekids. it/home/wp-content/plugins/all-in-one-event-calendar/lib/http/response/helper. php` is not available. If it’s there, it could be a permission issue. Can you copy here the relevant part of the log? * Thread Starter [sideways](https://wordpress.org/support/users/sideways/) * (@sideways) * [11 years, 4 months ago](https://wordpress.org/support/topic/php-fatal-error-require-failed-opening-required/#post-5679212) * not sure… this is the whole log: AH01215: PHP Fatal error: require(): Failed opening required ‘/web/htdocs/www.firenzekids.it/home/wp-content/plugins/all- in-one-event-calendar/lib/http/response/helper.php’ (include_path=’.:/php5.3/ lib/php/’) in /web/htdocs/www.firenzekids.it/home/wp-content/plugins/all-in-one- event-calendar/all-in-one-event-calendar.php on line 41 * asking for something else? sorry… * [Nicola Peluchetti](https://wordpress.org/support/users/nicolapeluchetti/) * (@nicolapeluchetti) * [11 years, 4 months ago](https://wordpress.org/support/topic/php-fatal-error-require-failed-opening-required/#post-5679216) * You said it gave you two errors.
