Issues with trying to change things in admin area

Hi there,
Im looking for some help with as issue Im having if possible. Im not too sure when this started happening or what I changed to trigger it unfortunatly.

This is the error message Im getting when Im trying to add a product:

Warning: define() expects at least 2 parameters, 1 given in /home/celynco1/public_html/personalimprint.co.uk/includes/languages/english/meta_tags.php on line 14

Warning: Cannot modify header information - headers already sent by (output started at /home/celynco1/public_html/personalimprint.co.uk/includes/languages/english/meta_tags.php:14) in /home/celynco1/public_html/personalimprint.co.uk/admin/includes/init_includes/init_templates.php on line 36

Warning: Cannot modify header information - headers already sent by (output started at /home/celynco1/public_html/personalimprint.co.uk/includes/languages/english/meta_tags.php:14) in /home/celynco1/public_html/personalimprint.co.uk/admin/includes/functions/general.php on line 21

Now Im assuming its related, everytime I go to change pretty much anything in admin Im getting very similar messages but by deleteting everything from the ? onwards in the URL Im usually able to get around it, but not to add products.

Anyone have any ideas?

Many Thanks
Dan

This looks like a warning causing a cascade of effects. SO you need to go back to the first event, the warning about the malformed define statement, it even tells you the file and line number in the warning, and fix that.

Thanks for the kick :) I've managed to sort it, seems I really messed up the Site tagline somehow.
