Error Message in Admin - Please Help!

[lprintz]

Hi guys!

I've poured over Google and the forums and couldn't find a resolution.

I'll try to be brief - had a client who's CMSMS site was perfectly fine and functional. Something happened on the host side that frigged things up.

Fortunately the db was intact so I did a reinstall. Now the site is fine but the admin is spitting out TONS of errors!

This seems to be the main one:
Warning: Cannot modify header information - headers already sent by (output started at /hermes/bosweb26c/b2706/ipw.watermarkenv/public_html/CMSMS/admin/lang/._en_US.nls.php:1) in /hermes/bosweb26c/b2706/ipw.watermarkenv/public_html/CMSMS/lib/classes/class.admintheme.inc.php on line 171

You can see the page here - www.watermarkenv.com/CMSMS/admin

I've tried uploading a fresh admin directory but to no avail. Can anybody help?

Thanks so much!

Looking at source for your admin log in page tell me you are hacked OR you have some files modified by you or someone else....

The files always starting with
<?php
and no white space or line breaks before this!

Start to upload a new
/admin/lang/._en_US.nls.php

Since the error report
/admin/lang/._en_US.nls.php:1
its error on line 1 in that file.
