.htaccess problem

Can someone tell me what is wrong with this code ?
i keep get an 500 internal server error whenever i use this

.htaccess

[code]Options -MultiViews +FollowSymlinks -Indexes

If mod_security is enabled, attempt to disable it.

- Note, this will work on the majority of hosts but on

MediaTemple, it is known to cause random Internal Server

errors. For MediaTemple, please remove the block below

# Turn off mod_security filtering. SecFilterEngine Off
# The below probably isn't needed, but better safe than sorry.
SecFilterScanPOST Off

MyBB “search engine friendly” URL rewrites

- Note, for these to work with MyBB please make sure you have

the setting enabled in the Admin CP and you have this file

named .htaccess

<IfModule mod_env.c>
	SetEnv SEO_SUPPORT 1
</IfModule>

If Apache is compiled with built in mod_deflade/GZIP support

then GZIP Javascript, CSS, HTML and XML so they’re sent to

the client faster.

AddOutputFilterByType DEFLATE application/x-javascript text/css text/html text/xml [/code]

Remove „+FollowSymlinks” from the Options directive.

removed it, still getting error.

try to remove everything, only keep
Options -Indexes
and all lines beginning with Rewrite

When this works, you can try to add the line AddOutputFilterByType
Then you can try to add the SetEnv-line, too

Thank you.
I’ll do this suggestion tomorrow and then post the results.
Hope it works ^^.
