I have my memory limit set to 512M in php.ini, but when I try to generate an XML sitemap using 4.0beta11 I get
PHP Fatal error: Allowed memory size of 268435456 bytes exhausted
That's 256M, but I don't have this defined anywhere....everywhere I could specify (php.ini, wp-config.php, .htaccess) I have set the memory limit to 512M, and a call to
ini_get('memory_limit') returns 512M.
The sitemap generation failure appears to be preventing the plugin from pinging Google after the sitemap is generated (or...not generated?).
What's happening here? Any ideas?
