Maximum function nesting level of 'xxx' reached, aborting! when live previewing

[novalex]

Redux 3.4.4.8, WP 4.1.1

I am getting this error when trying to live preview my theme on a fresh site. I've increased the xdebug maximum_nesting value until 400, same error. Going above that returned a "server connection reset" error. This only happens when the options are not saved to db, activating the theme works. I'm concerned that it might cause the reviewers to reject my theme. I found 2 similar issues here, one still open but decided not to piggyback.

Here is part of the error:

 Fatal error: Maximum function nesting level of '400' reached, aborting! in E:\Dropbox\DEV\WP\wp-includes\cache.php on line 497

The last 4 lines keep repeating until reaching the limit. I've tried turning the customizer off for all sections and then globally from the args, but no change.

Do this for me, update to the newest version of Redux found in this repo. Then go to the ~/wp-admin/tools.php?page=redux-support URL within your site. Click on Generate a Support Hash, then click I am a developer and give me the support URL please.

[dovy]

Actually, just read about it here: http://docs.reduxframework.com/core/generating-a-support-hash/

Hmm, it says "There was an error. Please try again later". I deactivated my firewall and antivirus without result.

I'm running WP on a WAMP local server, could this be the issue?

[dovy]

Shouldn't be. Could you please use chrome, click on the network tab, and tell me the error that's returned?

[dovy]

Ie, use a network inspector.

FYI @nova-ind, just tried Redux on the new WP beta. It's not in the core. It seems like something you're doing. I'll do my best to debug it soon after the 3.5 release.

[dovy]

Just tested you exact config without any problems. It's unfortunately somewhere in your theme. We can't dig into your code without Premium Support. Best of luck!

[novalex]

Normally, I would assume my theme is the cause as well, but this time it's definitely not the theme or even the config.
I've setup a new WP install, modified the TwentyFifteen theme to include Redux with the sample config and i get the same error when live previewing it. Again, once the theme is activated, switching to another theme and live previewing the one with Redux again, it works fine. It's something to do with the default options not being saved that causes this issue.
Please try this for yourself, just embed Redux into one of WP's themes and live preview it on a site where it's never been activated, I'm sure the error will rear its ugly head.

Please reopen the issue and i'll gladly do what i can on my end to help diagnose the cause, because every theme with Redux will get this error when previewing.

LE: Tested on TwentyThirteen also in hopes that this is caused by something only newer themes have in their code, but same outcome.

LLE: Forgot to mention, i've updated Redux to 3.4.4.9.1 before testing.

[dovy]

Ohhhhh. Live preview! Ok, on it!

[novalex]

Great, let me know if you need me to test anything on my environment!

[dovy]

Fixed and pushed. :)
