I was using the thumbnail gallery with PHP admin configured to PHP 5.2 on my server and everything was working fine until I upgraded. Once I changed the php version on my server to 5.3, I started to notice errors on the gallery page:
Warning: Cannot modify header information – headers already sent by (output started at /home/…/doptg/config.php:1) in /home/…/doptg/admin/index.php
Also on PHP 5.3 I’m unable to login on the admin side, I keep getting Error! Your username or password is invalid. Nothing is changed except the PHP version.
Please advise if they will be any updates to fix these issues for php 5.3
