.htaccess file bringing down website

Hi all,

I’ve been doing some maintenance work on a website. There are a few plugins being used and most were updated recently.

Before any updates are done on the live site I do them first on a duplicate site on the same server.

The most recent problem is that when the admin adds a new post, the .htaccess file seems to get overwitten and brings up an 500 error for the site.

This happened about an hour ago and I have the .htaccess file that caused the problem and a backup that fixes the problem.

The only difference I noticed in the 2 was that some code was misplaced. This is what it should be like:

# Increase cookie security
<IfModule php5_module>
  php_value session.cookie_httponly true
</IfModule>

# END HTML5 Boilerplate

# END WordPress

and this is what it gets changed too.

# Increase cookie security
<IfModule php5_module>
  php_value session.cookie_httponly true
</IfModule>

# END HTML5 Boilerplate

# END WordPress
pend to error (doesn't accept empty string, use whitespace if you need)
# php_value error_append_string " "

# Increase cookie security
<IfModule php5_module>
  php_value session.cookie_httponly true
</IfModule>

# END HTML5 Boilerplate

# END WordPress

As you can see it repeats and breaks the code in the .htaccess file (these are the last lines in the file).

Is there anything I can do to solve this?

I’ll also point out that the duplicate site has no problems.
