edit participant not functioning

Hard to say without knowing more. Are you able to look at your PHP error log? Do you know what PHP version you’re using?

I’m using version 5.3 (I can upgrade to 5.6)
I have no PHP error log (I can do that later).
But I forgot to mention, that before the edit function did work. I’m not sure at what point it failed, because I only found it out recently.

I see. It may be another plugin that was installed. The PHP version is fine, must be 5.2.

The error log will help figure this out.

Hi xnau,

Deactivating all other plugins didn’t solve the issue.
Here is the PHP error log. I hope this clears something up.

OK, this is what you see in the error log after attempting to load the record edit page in the backend? There is nothing there that would affect the display of the edit page. Try loading the edit page, then look at the error log.

When you attempt to load the record edit page, is it completely blank, or do you see the regular admin menu on the left? When you go go to the bottom of the page, do you see the WP footer that says “Thank you for creating with WordPress.”?

It’s an empty screen, but the footer is still visible:

here is a new error log, this time including messages from the edit page:

I tried to change the name of the field ‘extra functie(s)’ and I tried to erase the field, but I can’t.

I hope this makes sense to you! Thank you.

I see, you have an illegal field name, which you tried to do something about. Not sure how it got that way, but parentheses are not allowed in field names.

To fix this, you’ll need to edit the database tables using “phpMYAdmin” or something like that. Edit “wp_participants_database_fields” so that the name of the extra_functie field doesn’t contain a parentheses. After you change that, go to the “wp_participants_database” table and make sure the column name matches the name you used in the fields table.

Yes! That was it!
Strange how this problem came into existence. Maybe I’ve added those parentheses afterwards and haven’t been able to use the edit function ever since.
Thanks.
