same error as http://wordpress.org/support/topic/something-wrong-invalid-argument-and-cannot-modify-header?replies=2 apparently. What kind of image are you uploading, and did you change any of the options after updating?
Also, can you post the contents of the debug block on the settings page?
also should ask, are you on 1.2.0 or 1.2.1?
i have 1.2.1…also the image is a jpeg
i have tried it with about 10 different photos even a couple oi have already have on my site
i havent changed any options after updating
here is the debug info
jpegtran version: Independent JPEG Group’s JPEGTRAN, version 6b 27-Mar-1998
optipng version:
gifsicle version:
GD: OK
Imagemagick convert installed: NO
safe mode: Off
Operating System: Linux
exec(): enabled
getimagesize(): OK
mime_content_type(): OK
as it would turn out, it’s not really an ‘error’, but a variable I forgot to initialize. Unfortunately, it trickles down and breaks the output that is supposed to show up when you upload an image. I’ll have 1.2.2 out today.
I should have mentioned that you can also get rid of this error by turning off WP_DEBUG in your wp-config.php
i’m working on one more quirk for 1.2.2 but hopefully I’ll still get it out the door today.
