I have tried disabling google seo and friendly urls with this error still persisting.
This is my .htaccess:
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
#
<IfModule mod_security.c>
# Turn off mod_security filtering.
SecFilterEngine Off
# The below probably isn't needed, but better safe than sorry.
SecFilterScanPOST Off
</IfModule>
#
# 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_rewrite.c>
RewriteEngine on
RewriteRule ^user-([0-9]+)\.html$ member.php?action=profile&uid=$1 [L,QSA]
<IfModule mod_env.c>
SetEnv SEO_SUPPORT 1
</IfModule>
</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.

<IfModule mod_deflate.c>
