I have several add-on domains in my LP hosting account. One add-on domain in particular is running Wordpress. Let's say it's a folder at the root level of my LP account called /mywordpresssite

The default PHP upload limit is 2MB but I'd like to increase that. So I googled for it and found this official article:

http://wordpress.org/support/topic/increasing-max-filesize?replies=8

I tried putting this in the wp-config.php but it made no difference:

define(’WP_MEMORY_LIMIT’, ‘64M’);

Then it said you could put this in the dot-htaccess file:

php_value memory_limit 64M

but if I do that, the entire site stops working.

Any ideas? There are dot-htaccess files in both /mywordpress site and at the root level -- I'm not sure which I should be altering.

I tried a php.ini file both in /mywordpresssite and at the root level but couldn't get them to work.

Any ideas?
