As I press Customize: warning 'json_encode(): recursion detected' at /storage/content/

[tomas.risberg@…]

As I press Customize in Word Press 3.9 I recieve the error report enclosed. I have changed theme, and deactivated all my plugins, but nothing changes.

My server is using PHP 5.4.8

Backtrace from warning 'json_encode(): recursion detected' at /public_html/wp-includes/class.wp-scripts.php 170:

The error is repeated over and over.

Moving to 3.9 for investigation.

Couldn't replicate the issue on local installation of WordPress 3.9, PHP - 5.5.8. Also in the log I see a plugin /public_html/wp-content/plugins/easy-google-fonts/, Easy Google Fonts.

I apologize! I thought I removed all plugins before posting here. Google Easy fonts was updated some hours after the bug report, and then the backtrace report changed a bit - it shows just for a short while. I have now tracked the remaining problem to my use of an html5 modified theme.
