Make sure that your server has set the rights correctly. should be (on most linux server installations) 755 for folders and 644 for files (except root/ wp-config.php that should have 640 – i.e. not public read!). * I just installed Scheduler on my local linux server with wp 3.3.2 and everything works like a charm 🙂 * btw, we have used Scheduler on many projects – both this plugin and the main application at [http://dhtmlx.com/](http://dhtmlx.com/) (when we needed more than one calendar per site). We even used it to build a very advanced rotation calendar, with many users, for an health service institution. * I you have issues, go to their [forum](http://forum.dhtmlx.com/). They provide the best and fastest support we have ever experienced – for real. * regards, jaidesign * Thread Starter [grenzenlos](https://wordpress.org/support/users/grenzenlos/) * (@grenzenlos) * [14 years ago](https://wordpress.org/support/topic/plugin-event-calendar-scheduler/#post-2707272) * My Folder rights are all correct 755, and 644 config 640. it still works the problem is errors are showing and I can’t set rights for each member type. * I try there forums. * [Pankaj Asopa](https://wordpress.org/support/users/pankaj_asopa/) * (@pankaj_asopa) * [13 years, 10 months ago](https://wordpress.org/support/topic/plugin-event-calendar-scheduler/#post-2707310) * Don’t know about others, but I found this and solved this admin side issue * open file wp-content/plugins/event-calendar-scheduler/admin.php and modify the second line like here: * include(dirname(__FILE__).’/groups.php’); * see this : [http://forum.dhtmlx.com/viewtopic.php?f=16&t=24171](http://forum.dhtmlx.com/viewtopic.php?f=16&t=24171) * Thread Starter [grenzenlos](https://wordpress.org/support/users/grenzenlos/) * (@grenzenlos) * [13 years, 9 months ago](https://wordpress.org/support/topic/plugin-event-calendar-scheduler/#post-2707311) * Thanks pankaj_asopa * that did the trick Viewing 6 replies - 1 through 6 (of 6 total) The topic ‘[Plugin: Event Calendar / Scheduler]’ is closed to new replies. * ![](https://s.w.org/plugins/geopattern-icon/event-calendar-scheduler_fbefd8.svg) * [Event Calendar / Scheduler](https://wordpress.org/plugins/event-calendar-scheduler/) * [Frequently Asked Questions](https://wordpress.org/plugins/event-calendar-scheduler/#faq) * [Support Threads](https://wordpress.org/support/plugin/event-calendar-scheduler/) * [Active Topics](https://wordpress.org/support/plugin/event-calendar-scheduler/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/event-calendar-scheduler/unresolved/) * [Reviews](https://wordpress.org/support/plugin/event-calendar-scheduler/reviews/) * 6 replies * 5 participants * Last reply from: [grenzenlos](https://wordpress.org/support/users/grenzenlos/) * Last activity: [13 years, 9 months ago](https://wordpress.org/support/topic/plugin-event-calendar-scheduler/#post-2707311) * Status: resolved
