Mpff.. I again get those error messages :(
PHP Warning: Cannot modify header information - headers already sent by (output started at /qa-include/qa-base.php(510) : eval()'d code:1) in /qa-include/qa-page.php on line 363
I tried to find the mistake, I know that it could be UTF-8 instead of UTF8-without-BOM-encoding. But all files I checked were okay.
Line 363 of qa-page.php is: header('Content-type: '.$qa_content['content_type']); How can help?
All php files start with "<?php" and I could not find any file in pure "UTF8" encoding.
