Don't worry, i just took this up with DragonBall. Hopefully he'll shed some light.
*Pulls out hair* I am having this exact problem RIGHT NOW! Argh! So I guess everyone is saying if I host the image and use the url it will work? But why do we have to go through all of that?..... whats up with the upload in the avatar?
... Not Ever Again...
Am lost. I just tried uploading your problem avatar from photobucket and it worked. Weird.
Ah, now I'm having the same problem! The avatar I want to upload is 100x100 and is only 16.2 KB, but it still won't upload...it always says "upload of file failed".....
Please email me the file and I will also try.
All fixed. We hit the upload_max_filesize of 3GB on the server. Have increased this via editing the ini.php file for upload_max_filesize to 6GB.
In WHM, "service configuration" > PHP configurator Editor > Advanced.
Sorry to spit out tech babble, but wanted to write this down for future reference when it happens again.
Please try again and let me know if all is ok.
