Increase the PHP Memory Allocation and PHP Upload Size Limit for use with WordPress or Other Applications using .htaccess

Edit the .htaccess file in your root folder and add the following instructions. Don’t use an arbitrarily large value for memory values below and use just what you need and slowly increase it in increments (I use 16M for increments).

<IfModule mod_php5.c>
php_value post_max_size 32M
php_value upload_max_filesize 32M
php_value memory_limit 64M
</IfModule>
