Got it from this post

http://wordpress.org/support/topic/fatal-error-out-of-memory-messages?replies=24#post-1929111 , thought I’d share it with you guys :

?THIS TO BE ENTERED IN THE WP-CONFIG FILE WHICH IS IN THE ROOT OF THE WORDPRESS SETUP:
ENTER AFTER:?define(‘ABSPATH’, dirname(__FILE__).’/');
THE FOLLOWING:

define(‘WP_MEMORY_LIMIT’, ’64M’);

I ALSO CREATED A PHP.INI WHICH I UPLOADED TO THE PLUGIN FOLDER IN WP-CONTENT:

memory_limit = 128M; Maximum amount of memory a script may consume (64MB)
?max_execution_time = 45;?
upload_max_filesize = 10M;?
post_max_size = 20M;

Hope this helps!

Thank you for taking time to write this detailed post.

I’m a newbie and have been on this issue for more than 2 days already. I was creating multiple wordpress autoblog sites which always run cron scripts . This was my message.

Fatal error: Out of memory (allocated 66846720) (tried to allocate 35 bytes) in /home/maxlife/public_html/healthydinnerrecipesreview.com/wp-includes/meta.php on line 311

Tried the php.ini edit from 64 to 128M, and deleted unused plugins. Unfortunately, both didn’t work.

Then tried .htaccess route but I always get an internal server error.

Just wanted to run this by you guys to see if I did it correctly. This is how my htaccess looked like after the edit:

# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]

# uploaded files
RewriteRule ^files/(.+) wp-includes/ms-files.php?file=$1 [L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ – [L]
RewriteRule . index.php [L]
php_value memory_limit 128M
# END WordPress

So is this correct? How come I always get an internal server error when I edit the htacces file? Don’t really understand PHP codes so would really appreciate any guidance. Thanks a lot in advance.

This then actually modifies the file /home/mydomain/domains/mysubdomain.mydomain.com/etc/php5/php.ini for example.
