One of the problems I am experiencing with WordPress today is an out of memory php error with WordPress 2.8 when I use Arne Brachhold’s Google XML Sitemaps plugin to rebuilt my sitemap:
Fatal error: Allowed memory size of 16777216 bytes exhausted (tried to allocate 41 bytes) in /…/wp-settings.php on line 288
If I disable all my active plugins except Google XML Sitemaps, I don’t get the error when rebuilding the sitemap.
I am using Godaddy shared hosting, have added the line “memory_limit = 64M” in my php5.ini file and added the line ini_set(‘memory_limit’,’64M’); to my wp-config.php and I still get the error. I did not have this problem with WordPress 2.7.1.
I found this post by Jeff Starr, WordPress Error Fix(?): Increase PHP Memory for cache.php. Maybe his solution had to do with an Apache configuration – the post was written on February 17, 2008, so it wasn’t a WordPress 2.8 issue. Anyway I did the three things he mentioned, and things seem to be OK at the moment. I’m not going to pursue the problem anymore.
