Warning: Creating default object from empty value…

I have exactly the same problem, even when i switch back to twentytwelve i get the php warning.

i found out two things while figuring what was going wrong. first, i created a taxonomy-event-categories.php to do som special formating, still either php warning and some formating or no warning but then not formating 🙁

i followed all advice here, plugins off, switch them, make a lot of extra pages, used all templates in every possible order, still no luck.

i even went to the function in em-category-taxonomy -> function template($template)

and tried die(var_dump($template));

when i get the php warning $template is an empty string, when i get no warning, the template() function never runs

i could give more debug if somebody tells my what to do…

function template($template){
		die(var_dump($template));
		global $wp_query, $EM_Category, $em_category_id;

right there …

give me some hints what you need to debug and i will do

i created a file called ‘taxonomy-event-categories.php’ in my theme root same as ‘single-event.php’ for some theming reasons (i used to use simple-fields plugin to do some theming)

when my theme is rnning the taxonomy-event-categories.php, i dont get the object error but strangly, em-theming is not working… it just drops an unstyle eventlist:

Freitag, 8. März 2013 - Sonntag, 10. März 2013
16:00 - 18:00 Orality in James Joyce Conference
Arts Millenium Building, Galway Galway Freitag, 29. März 2013

The Crane Bar, Galway Galway Samstag, 1. März 2014
22:00 - 23:00 6 Nations, Italy VS Ireland

when i rename the file, i get this error (with wp debug enabled):

Warning: Creating default object from empty value in /wordpress/wp-content/plugins/events-manager/classes/em-category-taxonomy.php on line 22
Notice: Undefined property: stdClass::$ID in /wordpress/wp-includes/query.php on line 3385

but the em-theming is working at that point, but doing something strange in the loop. when i enabled the custom fields via simple-fields it was replacing all my content (even the custom vars) with the em-loop

i dont need the category page, so my dirty workaround is avoiding the category links everywhere…

@agelonwl the only plugin running right now is em.

i still get the
Warning: Creating default object from empty value in /wordpress/wp-content/plugins/events-manager/classes/em-category-taxonomy.php on line 22

when there is no file called: taxonomy-event-categories.php

when there is a file called taxonomy-event-categories.php the warning is gone but no em-themed event list

i could come to any irc channel to talk more about that problem, if neccessary

german, i hope you dont mind

nope because i am not sure how to use it in my custom-tax-**.php

anyways, i will not use categories in my site and activly prefent users to get there (header()-redirect )

Rather oddly, I have this problem in one of three copies of a site I’m testing. They’re on different servers, so I’m busy trying to determine whether there are any server settings that might cause one to throw the warning while the other two do not. (Edit: Yes, the server showing the message is set to display errors, and the others were not. The warning is displayed on all three now that I’ve alogned their settings more closely.)

I do have a plugin active that adds custom attributes to posts, including custom post types like events and locations, and initially I wondered whether the non-EM custom attributes were giving EM a problem…
