en WordPress.com Forums › Support Custom img header upload error Author Posts January 22, 2007 at 5:08 pm #51332 artchimpMember I am attempting to upload a new custom header image, but receive an error upon each upload. i’m taken to http://wp-admin/themes.php?page=custom-header&step=2 and the error in FF is: Server not found, Firefox can’t find the server at wp-admin. My image is an average filesize .jpg (about 30kb) I’m using Firefox v220.127.116.11 on XP Pro SP2. incidentally, i get a smiliar “page not found” when uploading an avatar, although i DO get to the cropping stage with this – the problem lies on http://wp-admin/avatar-upload.php?step=2 for me. Any help much appreciated – just purchased custom CSS and itching to progress! Author Posts The topic ‘Custom img header upload error’ is closed to new replies.
