In backend Entries > 'page-name' I could only see the left nav side bar, and the top "header" bar (breadcrumbs + page name + save button), when ever there was a Matrix field on the page.
I noticed that the last line rendered (marked in blue) had a height of 0, so I started poking around in the CSS.

After disabling a display: none; (marked in green below) for the div immediately below the last div shown, I could see part of the page plus the error message shown in the screenshot below.

enter image description here

To me, it looks like some "endless" recursion error.

Does anyone have any idea on what might be going on here?

Thanks in advance for any light you might shed on this!


Edit: added the top screenshot to show what the page looked like before I changed the CSS.

  • I've been dealing with this this morning too. Even the simplest Matrix field causes this recursion error. – Tim Knight Mar 15 '16 at 15:51
  • It's somewhat comforting to know that I'm not alone in this. <=) I hope we will have a solution to this soon! I'm heading home now, so no more trouble shooting on my part until tomorrow morning. =/ I'll post if I've heard anything from support when I'm back at the office. – CodeMonkey Mar 15 '16 at 16:01
  • Yup, that solution worked for me. – Tim Knight Mar 15 '16 at 17:12
  • Same here, see answer below. Cheers Brad! ^^ – CodeMonkey Mar 16 '16 at 7:48

Brad was right, it was xDebug that was the culprit. So here's what I did:

  1. In the Linux terminal I ran:

    sudo gedit /etc/php5/mods-available/xdebug.ini
  2. In the xdebug.ini file I added the line below and saved.

  3. In the Linux terminal I ran:

    sudo service apache2 restart


Note: if the this does not fix it, try changing the command in step 1 to:

sudo gedit /etc/php5/conf.d/xdebug.ini

or just edit your php.ini file where ever it may be located.
