Either all Options must start with + or -, or no

Directory Options

If you had Directory options, note that they all have to be prepended with a + or - or none of them at all. A mix of both is not allowed:

Example:

This is allowed:

<Directory /path/to/your/site/>
    Options +Indexes +FollowSymLinks -MultiViews
</Directory>

So is this (Note that these examples don't both do the same thing, the previous one disables the MultiViews option, the next one doesn't):

<Directory /path/to/your/site/>
    Options Indexes FollowSymLinks MultiViews
</Directory>

This is no longer allowed:

<Directory /path/to/your/site/>
    Options Indexes FollowSymLinks -MultiViews
</Directory>

Last config option will throw the a syntax error saying:

Either all Options must start with + or -, or no Option may.
