Conflict with Quick Tabs plugin

I’m using Quick Tabs plugin and all is working fine, except the EE Event Overview page. The right hand column, which includes the Update Event button, does not display, making it impossible to update basic event info such as start and end times. When I deactivate the Quick Tabs plugin, the event Overview page works fine, but I need both plugins (unless anyone can suggest another plugin for tabs – this is the only one I’ve found that works with WP 3.5 and allows me to customize styles).

Here’s what displays at the very bottom of the Event Overview page when Quick Tabs is activated:

Warning: require_once(includes/meta-boxes.php) [function.require-once]: failed to open stream: No such file or directory in […]/wp-content/plugins/event-espresso/includes/admin-files/event-management/edit_event_post.php on line 69

Fatal error: require_once() [function.require]: Failed opening required ‘includes/meta-boxes.php’ (include_path='[…]/wp-content/plugins/quick-tabs/’) in […]/wp-content/plugins/event-espresso/includes/admin-files/event-management/edit_event_post.php on line 69

Hi Adelaide,

I think there may be another plugin or theme function that is conflicting between Event Espresso and the Quick Tabs plugin. I have installed Quick Tabs and on my test site and I am not able to reproduce this. You might try leaving the two plugins activated, then deactivate other plugins to see if that makes any difference.

Hi Josh. The only other plugin I’m using is Typekit Fonts,and deactivating it didn’t make a difference. I have an Artisteer theme installed.

Hi Adelaide,

You can rule out a theme function conflict by temporarily switching to another theme like twentytwelve or twentyeleven. The theme test drive plugin plugin is recommended if you’d to try the other theme without actually disabling your Artisteer theme.

Ruled out theme function conflict – switched to twentytwelve and conflict didn’t go away.

Hi Adelaide,

Thanks for checking. I did some checking on my end and I think I have a solution for you. In this case, I couldn’t reproduce the issue when running the two plugins on a server that had PHP 5.4 installed. When I switched to PHP 5.2.17, I could.

The conflict appears to be where quicktags is declaring its own includes directory in quick-tabs.php on line 13:


This can be worked around by adding the wp-admin path to both lines 69 of edit_event_post.php and line 40 of new_event_post.php. You can add this by changing them from:

require_once( 'includes/meta-boxes.php');


require_once(ABSPATH . 'wp-admin/includes/meta-boxes.php');

If this works for you please let us know and we can include this in a future update.
