That’s the error I got when using Visual Composer’s Posts Grid element on a long and involved post. It did not happen when displaying the post through the single.php or archive.php templates – only the Visual Composer element.
After some searching, I came across this as a workaround:
Basically, it turns out that I can disable the error by going into my php.ini file and commenting out this line:
zend_extension = "d:/wamp/bin/php/php5.4.12/zend_ext/php_xdebug-2.2.3-5.4-vc9-x86_64.dll"
Alternatively, increasing the limit in of the nesting level works too – like this in php.ini:
xdebug.max_nesting_level = 200
