Title: [Plugin: Events Manager] Upgrade 4.0.4 Last modified: August 20, 2016 --- # [Plugin: Events Manager] Upgrade 4.0.4 * Resolved [dokauai](https://wordpress.org/support/users/dokauai/) * (@dokauai) * [15 years ago](https://wordpress.org/support/topic/plugin-events-manager-upgrade-404/) * I was following the screencast step by step and got to 3:45 when i got a “500. htm” in the white box. Now WP is locked up. I can not access WP admin or the site itself. Any suggestions on how to proceed? * [http://wordpress.org/extend/plugins/events-manager/](http://wordpress.org/extend/plugins/events-manager/) Viewing 11 replies - 1 through 11 (of 11 total) * Plugin Author [Marcus (aka @msykes)](https://wordpress.org/support/users/netweblogic/) * (@netweblogic) * [14 years, 12 months ago](https://wordpress.org/support/topic/plugin-events-manager-upgrade-404/#post-2083937) * is this in 4.0.4? * Thread Starter [dokauai](https://wordpress.org/support/users/dokauai/) * (@dokauai) * [14 years, 12 months ago](https://wordpress.org/support/topic/plugin-events-manager-upgrade-404/#post-2083985) * Yes, 4.0.4, i was locked out of WP altogether. * I deleted the EM folder which allowed me back into WP. I then installed 3.0.98 and all the events were back, but it would not allow me to add a new event… ‘ Could not save the event details due to a database error.’ So i upgraded to 4.0.5 and it said it was successful, but then it closed that window and sent me to the WP Login page, which then gave a ‘500.htm’ message, and locked me out. I put 3.0.98 back so people can see events, but i have been making changes in EM every week for almost two years and am not ready to lose a good thing. How should i proceed? * Plugin Author [Marcus (aka @msykes)](https://wordpress.org/support/users/netweblogic/) * (@netweblogic) * [14 years, 11 months ago](https://wordpress.org/support/topic/plugin-events-manager-upgrade-404/#post-2084002) * First step, have you checked the upgrade walkthrough? [http://wp-events-plugin.com/news/upgrade-issues-screencast-walkthrough/](http://wp-events-plugin.com/news/upgrade-issues-screencast-walkthrough/) * Then you need to import bookings, go to your Event settings page after installing. FYI, I just rewrote the import script today for bookings, which’ll go into the next update. I advise you wait for that (or try the dev version, i updated it just now) * Thread Starter [dokauai](https://wordpress.org/support/users/dokauai/) * (@dokauai) * [14 years, 11 months ago](https://wordpress.org/support/topic/plugin-events-manager-upgrade-404/#post-2084035) * I tried 4.0.6 with basically the same results. The installation stalls out, and then it gives me a blank white page. I can go to the website and see that a new version has been installed, but i can not go to WP admin to add a post, or to add an event, or go to the events settings page, or do anything at all. I am locked out of WP until i re-install 3.0.98. * Plugin Author [Marcus (aka @msykes)](https://wordpress.org/support/users/netweblogic/) * (@netweblogic) * [14 years, 11 months ago](https://wordpress.org/support/topic/plugin-events-manager-upgrade-404/#post-2084037) * we’ll be releasing a new update but I’m not sure this will help you. if you follow the instructions, it should work. * When you get the 500 error, do you get any errors in your php logs? * Thread Starter [dokauai](https://wordpress.org/support/users/dokauai/) * (@dokauai) * [14 years, 11 months ago](https://wordpress.org/support/topic/plugin-events-manager-upgrade-404/#post-2084048) * With 4.0.6 i did not get a 500.htm, just a blank white screen. * There are about 20 errors that start out the same as these two. * 1) Too many keys [04-Jun-2011 12:32:21] WordPress database error Too many keys specified; max 64 keys allowed for query ALTER TABLE wp_em_tickets_bookings ADD INDEX (ticket_id) made by require_once, require_once, require_once, require_once, do_action, call_user_func_array, em_init, em_install, em_create_tickets_bookings_table, dbDelta * 2) Unknown column [04-Jun-2011 12:41:20] WordPress database error Unknown column‘ event_seats’ in ‘wp_em_events’ for query ALTER TABLE wp_em_events CHANGE event_seats event_spaces int(5) made by require_once, require_once, require_once, require_once, do_action, call_user_func_array, em_init, em_install, em_create_events_table * I will try 4.0.7 when it comes out. But if that doesnt work, i cant use 3.9.8, and i cant use 4.0.6, so please tell me what to delete (even if it means losing everything) so i can start over with a clean 4.0.x. Or, i would be more than happy to pay you for extra help to resolve this. * [AdventuresNW](https://wordpress.org/support/users/adventuresnw/) * (@adventuresnw) * [14 years, 8 months ago](https://wordpress.org/support/topic/plugin-events-manager-upgrade-404/#post-2084078) * Same thing happened to me. Install hangs and then white screen on both the home page and admin page preventing any reversal. I’d say this does not work. * Plugin Author [Marcus (aka @msykes)](https://wordpress.org/support/users/netweblogic/) * (@netweblogic) * [14 years, 8 months ago](https://wordpress.org/support/topic/plugin-events-manager-upgrade-404/#post-2084079) * there’s an issue with the home screen not working if you assign the Events Page, haven’t had a chance to look into this yet. * there’s a problem with dbdelta and adding keys when they already exist. in theory it shouldn’t add extra keys but it does. looking into this too * if you go into your db and delete the indexes manually, that’ll fix that issue for now. * Plugin Author [Marcus (aka @msykes)](https://wordpress.org/support/users/netweblogic/) * (@netweblogic) * [14 years, 8 months ago](https://wordpress.org/support/topic/plugin-events-manager-upgrade-404/#post-2084080) * just fixed this in the dev version, it should prevent adding duplicates and also remove the duplicate keys. * update may take longer than usual if you have lots of duplicate keys. this should probably speed things up a bit for some * [thatmtnman](https://wordpress.org/support/users/thatmtnman/) * (@thatmtnman) * [14 years, 8 months ago](https://wordpress.org/support/topic/plugin-events-manager-upgrade-404/#post-2084082) * Not sure if this is the right place to post a bug, but the most recent version of events manager seems to require a date picker (which I presume to be a little java or ajax calendar of some description). * However, there is no such ‘date picker’ in my install. So when I try to manually enter the date, the predictable ‘can’t do that, please use the date picker’ type of error shows up. * Can anyone help? * Plugin Author [Marcus (aka @msykes)](https://wordpress.org/support/users/netweblogic/) * (@netweblogic) * [14 years, 8 months ago](https://wordpress.org/support/topic/plugin-events-manager-upgrade-404/#post-2084083) * you probalby have a conflicting theme or plugin preventing the datepicker from showing up Viewing 11 replies - 1 through 11 (of 11 total) The topic ‘[Plugin: Events Manager] Upgrade 4.0.4’ is closed to new replies. * ![](https://ps.w.org/events-manager/assets/icon-256x256.png?rev=1039078) * [Events Manager - Calendar, Bookings, Tickets, and more!](https://wordpress.org/plugins/events-manager/) * [Frequently Asked Questions](https://wordpress.org/plugins/events-manager/#faq) * [Support Threads](https://wordpress.org/support/plugin/events-manager/) * [Active Topics](https://wordpress.org/support/plugin/events-manager/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/events-manager/unresolved/) * [Reviews](https://wordpress.org/support/plugin/events-manager/reviews/) * 11 replies * 4 participants * Last reply from: [Marcus (aka @msykes)](https://wordpress.org/support/users/netweblogic/) * Last activity: [14 years, 8 months ago](https://wordpress.org/support/topic/plugin-events-manager-upgrade-404/#post-2084083) * Status: resolved
