On suphp servers  you should remove the lines from .htaccess file that begin with “php_value” and “php_flag”. You will need to add the settings that you want to use to a file named php.ini and upload php.ini into your public_html directory.

You will need to remove php_value and php_flag from ALL .htaccess files you may have

In .htaccess under public_html, add the following:

suPHP_ConfigPath /home/AccountUserName/public_html
<Files php.ini>
order allow,deny
deny from all
</Files>

In php.ini under public_html add the settings that you want to use:

register_globals = On
post_max_size 6M
upload_max_filesize 6M
max_execution_time 90
max_input_time 90

To redirect ALL files on your domain use this in your
.htaccess file if you are on a linux web server:

redirectMatch 301 ^(.*)$ http://www.site.net
redirectMatch permanent ^(.*)$ http://www.site.net

You can also use one of these in your .htaccess file:

redirect 301 /index.php http://www.site.net/index.php
redirect permanent /index.php http://www.site.net/index.php
redirectpermanent /index.php http://www.site.net/index.php

If you need to redirect http://site.net to http://www.site.net and you’ve got mod_rewrite enabled on
your server you can put this in your .htaccess file:

Options +FollowSymLinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^site\.net
RewriteRule ^(.*)$ http://www.site.net/$1 [R=permanent,L]

I was recently surprised to see that my wordpress install folders have swelled up in size like anything. I have 3 installs of WP and I noticed that in the root of each install there were dump files with a name pattern “core.*” and with sizes to the tune of 12MB each.

core files come from a core dump. A core dump can happen for lots of reasons, but in shared hosting it generally occurs if:

1. Your site software is not compatible with the latest server software versions.

2. The server software itself was/is having issues.

• Check the content of the core dump files for clues. It is probably because one of your binaries (i.e. unzip, imagemagick) is not working correctly. If the core files point back to php, then it could be a a memory limit problem, a g2 bug, or a php bug.
• Try a clean install of WordPress (delete all old files, re-upload, new, empty database). Make sure you backup your blog (export all posts and also back up the database).
• ( System Administrator ) -  You can stop core files from being produced as a result of suPHP and Rlimit stoppages. In /etc/init.d/httpd at the top of the file you’ll see the ulimit command line. Add a “-c 0″ (slash-c-zero) to the line:
  Code:

  ulimit -c 0 -n x

  where the x above is the number previously assigned by your Rlimit script. That should stop core dump files
