Increase Wordpress WXR (.xml) Import Max File Size?
<p>When importing a WXR (.xml) file from the Wordpress import screen under tools to pull in a backup of posts/pages/etc. it says Max File size is 8mb.  Of course most sites of size will have much larger files and I am having trouble figuring out how to increase that.</p>

<p>I have tried the following:</p>

<p>added to php.ini file:</p>

<pre><code>php_value upload_max_filesize 50M
php_value post_max_size 50M
</code></pre>

<p>added the following to functions.php file:</p>

<pre><code>@ini_set( 'upload_max_size' , '50M' );
@ini_set( 'post_max_size', '50M');
</code></pre>

<p>added to the wp-donfig.php file:</p>

<pre><code>define('WP_MEMORY_LIMIT', '64M');
</code></pre>

<p>added to .htaccess:</p>

<pre><code>php_value upload_max_filesize 64M
php_value post_max_size 64M
php_value max_execution_time 300
php_value max_input_time 300
</code></pre>

<p>None one of these seem to be where the limit is coming from.  Any help on increasing the limit would be greatly appreciated.  Thank you in advance for your answers.</p>
