help captcha

hi there,

Why if I do this (http://www.boonex.com/m/FREE_MOD_DeeEmm_Hide_Menu_Bar_from_Guests) or this(http://www.boonex.com/m/remove-search-from-top-menu-2011-08-30) changes, the captcha does not work and to the folder /simg/ it create an error_log  with any errors about this:

PHP Warning:  Cannot modify header information - headers already sent by (output started at /home2/mycommunity/public_html/templates/base/scripts/BxBaseMenu.php:1792) in /home2/mycommunity/public_html/inc/images.inc.php on line 141

???

excuse my bad English and thank you all!!

The first link, to remove the search from top menu, ....

Compatibility: Dolphin: 7.0.3

and the second one,

Compatibility: 7.0.2    DeeEmm is not active here much anymore.

What version of Dolphin are you using?

also found this somewhere else....
