=== WP Memory Limit ===
To increase the memory limit for wordpress you should first change the php.ini file.
\\
\\
If that does not work you should add the following to your wp-config.php file
<sxh bash>
define( 'WP_MEMORY_LIMIT', '96M' );
</sxh>
Change the memory limit value as required

=== Changing Site URL ===
Check the current URL, first select the database with the 'use' command (eg. use live_database;):
<sxh bash>
SELECT * FROM wp_options WHERE option_name = 'siteurl' OR option_name = 'home' ;
</sxh>
Now we can update the URL:
<sxh bash>
UPDATE wp_options SET option_value = 'http://lukeslinux.co.uk' WHERE option_name = 'siteurl' OR option_name = 'home';
</sxh>
\\
=== Deterring wp-login attacks ===
Add the following to your htaccess.

The following code stops any ip address posting to your wp-admin page that does not have a referrer or user-agent set.

An example log entry is:
<sxh bash>
x.x.x.x - - [23/Aug/2016:17:25:40 +1000] "POST /wp-login.php HTTP/1.0" 403 214 "-" "-"
</sxh>
Code:
<sxh bash>
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{REQUEST_METHOD} POST
RewriteCond %{HTTP_REFERER} !^https://(.*)?reaa\.com\.au [NC]
RewriteCond %{REQUEST_URI} ^(.*)?wp-login\.php(.*)$ [OR]
RewriteCond %{REQUEST_URI} ^(.*)?wp-admin$
RewriteRule ^(.*)$ - [F,L]
</IfModule>
