[resolved] Wp-admin error after moving WordPress (3 posts)

    Hello.

    I have followed the tutorial http://codex.wordpress.org/Moving_WordPress to move my WordPress from one domain to another.

    When I did this everything worked well, until I tried to log in to the Dashboard. Now I can't log into neither of my blogs and I am very afraid that my blog is broken!?!

    How can I fix this without deleting the content and the design I have worked five weeks with?

    The php error message I get when I open /wp-login.php:

    Warning: Cannot modify header information - headers already sent by (output started at /customers/aichandmokie.com/aichandmokie.com/httpd.www/wp/wp-content/plugins/flv-embed/flv-embed.php:2561) in /customers/aichandmokie.com/aichandmokie.com/httpd.www/wp/wp-login.php on line 290

    and when I try to log in:

    Warning: Cannot modify header information - headers already sent by (output started at /customers/aichandmokie.com/aichandmokie.com/httpd.www/wp/wp-content/plugins/flv-embed/flv-embed.php:2561) in /customers/aichandmokie.com/aichandmokie.com/httpd.www/wp/wp-login.php on line 290

    I wonder if the problem is that the plugins was active when I exported the database and the entire worpress installation. If that created the problem the tutorial at WordPress should def said something about 'turn all plugins off before starting this procedure'

    Please help me to solve my problem!

    Never mind ;)

    This explanation gave me the correct directions to look for errors.

    Interpreting the Error Message:

    If the error message states: Warning: Cannot modify header information - headers already sent by (output started at /path/blog/wp-config.php:34) in /path/blog/wp-login.php on line 42, then the problem is at line #34 of wp-config.php, not line #42 of wp-login.php. In this scenario, line #42 of wp-login.php is the victim. It is being affected by the excess whitespace at line #34 of wp-config.php.

    If the error message states: Warning: Cannot modify header information - headers already sent by (output started at /path/wp-admin/admin-header.php:8) in /path/wp-admin/post.php on line 569, then the problem is at line #8 of admin-header.php, not line #569 of post.php. In this scenario, line #569 of post.php is the victim. It is being affected by the excess whitespace at line #8 of admin-header.php.
