Help needed please. Cannot modify header information - headers already sent by
 

Hoping someone can help

Site suddenly went down in the small hours of the night. No files had been changed.

The error message is

Cannot modify header information - headers already sent by (output started at /home/s*****/public_html/dbtech/dbseo/includes/class_db:865)

I've spent plenty of time on google, reading about white space, which I cannot find, and in any case, the site was fine one moment, than failed the next.

Version is 4.2.3patch

Line 865 in public_html/dbtech/dbseo/includes/class_db is
if (!$connect = $this->functions['connect']($link, $servername, $username, $password, '', $port))

Did you host update your php version by any chance ?

No Paul - it's native 5.4 and has been for a few months. Unless they have altered something behind the scenes that I'm not aware of - but I will ask the question.

Well someone altered something, thats for certain.

It cannot just suddenly fail on its own, for no reason.

I am seeing this error which is something you need to show your host:

Closing this, its duplicated on vb.com so its just confusing and wasting people time.
