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

[Phil Dart]

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 ?

[Phil Dart]

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.

[Paul M]

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:

mysqli_real_connect(): Headers and client library minor version mismatch. Headers:50633 Library:50552

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