Title: Fatal error when changing end date Last modified: August 30, 2016 --- # Fatal error when changing end date * Resolved [scott1137](https://wordpress.org/support/users/scott1137/) * (@scott1137) * [11 years ago](https://wordpress.org/support/topic/fatal-error-when-changing-end-date/) * I tried to change the end date of a recurring series of events. I’ve done this many times but haven’t for months. * I receive this: * > Fatal error: Class ‘Tribe__Events__Pro__Date_Series_Rules__Rules_Interface’ > not found in /home2/soslsj/public_html/wp-content/plugins/the-events-calendar/ > src/Tribe/Date_Utils.php on line 224 * Suggestions? Thanks * [https://wordpress.org/plugins/the-events-calendar/](https://wordpress.org/plugins/the-events-calendar/) Viewing 4 replies - 1 through 4 (of 4 total) * [Brook](https://wordpress.org/support/users/brook-tribe/) * (@brook-tribe) * [11 years ago](https://wordpress.org/support/topic/fatal-error-when-changing-end-date/#post-6313033) * Thanks for sharing the error scott1137. Would you mind grabbing your system information and pasting it here? Feel free to redact private info, but know that the more you share the better. You can find the system info by going to WP Admin > Events > Settings, clicking on the “Help” tab, and scrolling down to the ‘System Information’ box. (Or by going to [yoursite]/wp-admin/edit.php?post_type=tribe_events&page =tribe-events-calendar&tab=help) That will give me a lot of extra information to help diagnose the problem. * Cheers! – Brook * Thread Starter [scott1137](https://wordpress.org/support/users/scott1137/) * (@scott1137) * [11 years ago](https://wordpress.org/support/topic/fatal-error-when-changing-end-date/#post-6313046) * Hi Brook * I paid my license and went to the Calendar Pro forum where Brian suggested I update to latest version. I had overlooked that and when I did, found I could edit the end and update without errors. * The end date edit update showed correctly in the calendar but not in the All Events List. * Also that list starts at the beginning of the events series. Would prefer it start with current events. * I’ve posted an update to Brian about these issues. I’m posting here for completeness in case it might help others. Feel free to help me solve the issues here, or not. * Thank you, Scott * Here’s system information: * [http://www.soslsd.org](http://www.soslsd.org) install keys * events-calendar-pro = 47b1c609b457d93b4d00c6ac7aa4e65e1cf4ef87 * WordPress version 4.2.2 PHP version 5.3.29 plugins * Advanced Custom Fields version 4.4.2 by Elliot Condon([http://www.elliotcondon.com/](http://www.elliotcondon.com/)) Akismet version 3.1.3 by Automattic([http://automattic.com/wordpress-plugins/](http://automattic.com/wordpress-plugins/)) All in one Favicon version 4.3 by Arne Franken([http://www.techotronic.de/](http://www.techotronic.de/)) BackWPup version 3.1.4 by Inpsyde GmbH([http://inpsyde.com](http://inpsyde.com)) Broken Link Checker version 1.10.9 by Janis Elsts([http://w-shadow.com/](http://w-shadow.com/)) Better WordPress Minify version 1.3.3 by Khang Minh([http://betterwp.net](http://betterwp.net)) Custom Post Type UI version 1.1.1 by WebDevStudios([http://webdevstudios.com/](http://webdevstudios.com/)) Custom Post Widget version 2.7.7 by Johan van der Wijk([http://vanderwijk.nl](http://vanderwijk.nl)) Edit Flow version 0.8 by Daniel Bachhuber, Scott Bressler, Mohammad Jangda, Automattic, and others([http://editflow.org/](http://editflow.org/)) The Events Calendar PRO version 3.10.1 by Modern Tribe, Inc.([http://m.tri.be/20](http://m.tri.be/20)) Google Analytics by Yoast version 5.4.2 by Team Yoast([https://yoast.com/](https://yoast.com/)) Gravity Forms CSS Ready Class Selector version 1.1 by Brad Vincent([http://themergency.com/](http://themergency.com/)) Gravity Forms + Custom Post Types version 3.0.1 by Brad Vincent([http://themergency.com/](http://themergency.com/)) Gravity Forms version 1.9.11 by rocketgenius([http://www.rocketgenius.com](http://www.rocketgenius.com)) Gravity Forms PayPal Add-On version 1.10 by rocketgenius([http://www.rocketgenius.com](http://www.rocketgenius.com)) Jetpack by WordPress.com version 3.6 by Automattic([http://jetpack.me](http://jetpack.me)) Latest Custom Post Type Updates version 1.3.0 by David Wood([http://technicalmastermind.com/about-david-wood/](http://technicalmastermind.com/about-david-wood/)) NextGEN Gallery by Photocrati version 2.1.0 by Photocrati Media([http://www.photocrati.com](http://www.photocrati.com)) PayPal Donations version 1.8.9 by Tips and Tricks HQ, Johan Steen([https://www.tipsandtricks-hq.com/](https://www.tipsandtricks-hq.com/)) Permalink Editor version 0.2.12 by Fubra Limited([http://fubra.com](http://fubra.com)) Redirection version 2.3.16 by John Godley([http://urbangiraffe.com](http://urbangiraffe.com)) Responsive Select Menu version 1.6 by Chris Mavricos, SevenSpark([http://sevenspark.com](http://sevenspark.com)) The Events Calendar version 3.10.1 by Modern Tribe, Inc.([http://m.tri.be/1x](http://m.tri.be/1x)) TinyMCE Advanced version 4.1.9 by Andrew Ozz([http://www.laptoptips.ca/](http://www.laptoptips.ca/)) Wordfence Security version 6.0.10 by Wordfence([http://www.wordfence.com/](http://www.wordfence.com/)) WordPress SEO version 2.2.1 by Team Yoast([https://yoast.com/](https://yoast.com/)) WP Smush version 2.0.6.1 by WPMU DEV([http://premium.wpmudev.org/](http://premium.wpmudev.org/)) WordPress Zero Spam version 2.0.1 by Ben Marshall([https://benmarshall.me](https://benmarshall.me)) * network plugins – mu plugins – theme BootstrapWP multisite – settings * disable_metabox_custom_fields = show welcome_notice = 1 previous_ecp_versions = * Array ( [0] => 0 [1] => 2.0.11 [2] => 3.0 [3] => 3.0.3 [4] => 3.1 [5] => 3.2[ 6] => 3.3 [7] => 3.3.1 [8] => 3.4 [9] => 3.4.1 [10] => 3.5 [11] => 3.5.1 [12] => 3.6.1 [13] => 3.8.1 [14] => 3.9.1 [15] => 3.9.2 [16] => 3.9.3 [17] => 3.10) * latest_ecp_version = 3.10.1 displayedPressTrendsDialogue = 1 donate-link = viewOption = list eventsSlug = support-groups singleEventSlug = support-group postsPerPage = 10 showComments = multiDayCutoff = 12:00 embedGoogleMaps = 1 embedGoogleMapsHeight = 350 embedGoogleMapsWidth = 100% embedGoogleMapsZoom = 8 sendPressTrendsData = debugEvents = defaultValueReplace = defaultCountry = * Array ( [0] => US [1] => United States ) * recurring_events_are_hidden = exposed stylesheetOption = tribe tribeEventsTemplate = page-events.php tribeEnableViews = * Array ( [0] => list [1] => month [2] => map [3] => photo ) * tribeDisableTribeBar = hideLocationSearch = tribeEventsBeforeHTML = Our SOSL Support Groups provide a comfortable, non-threatening setting to share your experiences and thoughts. Or you may just want to listen. But being with those who have had a similar experience, who can understand in a special way, is a gift the group shares with one another, a gift that may not be available elsewhere. Anyone who has lost a family member or friend is invited to attend. All groups are free of charge and no prior registration is needed. All of the groups listed on the calendar are conducted by SOSL and are not affiliated with the venue listed, e.g. hospital, community center, church, etc. [_Read more_](https://wordpress.org/support/?output_format=md).
