Can´t modify products without error

Hello!

I cannot solve this problem, I really hope someone can help me;
"Warning: Cannot modify header information - headers already sent by (output started at /customers/d/5/2/skycraft.se/httpd.www/admin/language/swedish/catalog/product.php:1) in /customers/d/5/2/mypage.se/httpd.www/system/engine/controller.php on line 28Warning: Cannot modify header information - headers already sent by (output started at /customers/d/5/2/mypage.se/httpd.www/admin/language/swedish/catalog/product.php:1) in /customers/d/5/2/mypage.se/httpd.www/system/engine/controller.php on line 29"

I think it is easy for someone to solve, but not for me.. Thank you in advance!

Best regards Erik

hi Erik

That issue will be due to whitespace in the file it references (admin/language/swedish/catalog/product.php)
Open that file, and make sure there is nothing before the <?php including spaces and carriage return lines. Then save and it should work

have same error msg. cannot login into admin panel. did remove white space and uploaded as ascii, not solved.

Upload as binary not ASCII for ALL files always
