WordPress 4-letter comment error -

WordPress 4-letter comment error -

this 1 of weirdest bugs i've seen. uploaded wordpress onto 1 of new sites, http://viewmixed.com/, , there unusual bug when posting four-letter words.

at first thought couldn't leave comments @ because kept trying leave comment word "test". realized 4 letter word seems break comments i.e. "four" or "1234", other string posts comment fine.

i have tried deleting files/database , re-installing wp, , didn't solve anything. i'm on newest wp version, 3.5.1, , tried installing 3.4.2 , 3.1.4, none fixed issue...

anyone have thought of going on?

edit: forgot mention have custom theme right now, bug there before installing theme, , tried changing themes, 4-letter bug doesn't go away.

it's not easy reply in detail because there couple of reasons getting error, can see in title there error 406 not acceptable mod_security problem.

frist alter permalink settings within wordpress , if error still appears.

second seek deactivate mod_security. hence can add together .htaccess file within wp-admin directory...

<ifmodule mod_security.c> secfilterscanpost off </ifmodule>

...or add together .htaccess file within root disable completely:

<ifmodule mod_security.c> secfilterengine off </ifmodule>

if still not work suggest contact hosting provider you.

as not easy find solution (and farther reading) suggest reading this blogpost on finding 406 error , this blogpost similar solution within wordpress.

hopefully might helpful you.
