Blank screen when saving Registration Custom Questions to Question Groups

So I’m adding a few custom questions to the event registration form, then go to Question Groups and tick the box assigning it to chosen group. However, when I save the screen just goes blank, and my save isn’t applied to the questions.

Any ideas?

Hi Jai,

Can you enable WP_DEBUG and then retry this please.

Are there any error messages shown on the whitescreen once WP_Debug has been enabled?

Hi Tony, I’m working on a live site, so can’t really enable WP_DEBUG.

Have you modified Event Espresso at all?

This notice means a widget is being incorrectly initialized, however it could be within the theme or a plugin.

This is usually caused by either the theme or a plugin altering the query within the EE pages. However to troubleshoot this you’ll need to disable all non-EE plugins and re-test, as you mentioned your currently using a live site I would highly recommend creating a development copy of the site to troubleshoot on. This can be either locally or within a sub-domain/directory on your server.

Thanks Tony, no I’ve not modified any of the EE files. I’ll try your suggestion.

Just to note, when you disable all non-EE plugins, switch to one of the default themes and test first.

This checks that it is not a theme conflict before moving through each of the plugins only to find it was the theme causing the problem.

Hi Tony, I removed all the plugins, but the issue still occurred. I’m not comfortable with copying site (or switching to another theme on the live site, as worried of losing custom changes). Any other suggestions?

Hi Jai,

If you can send a copy of the theme to us we can load it onto a test site. {support at eventespresso.com}

It doesn’t appear to be an issue caused by the WordPress theme. I loaded up the theme files you sent and activated the theme on a test site. Then I tested adding some questions to a question group and the group updated when I hit save with no blank screen.

Can you export the database and send a copy so we can investigate further?

Thanks for sending, being able to look at the questions and question groups database tables most certainly helps. I’ll update this thread with more information as we look into this further.

Update: They made some under the hood changes to avoid the issue you saw before, and the changes are included in the latest update. Basically what happened was when the database incremented the question ID’s it was using an interval like 1,3,5. Event Espresso 4 was expecting 1,2,3. The changes in Event Espresso 4.8.10.p allows for more flexibility there.

Please let us know if there’s anything else we can do to help.
