as I had follow instruction replace the code to the Function_posting.php and user.php
change to avatar setting to
1) file size 262144 (default 30614)
2) max avatar size: 150x140 (default 90x90)
after clear all cookies, UCP edit avatar upload a jpg file(254K) and message as below:
"The submitted avatar is 813 pixels wide and 814 pixels high. Avatars must be at least 20 pixels wide and 20 pixels high, but no larger than 150 pixels wide and 150 pixels high."
This is the same issue before modifying the above two files!
Secondly, what is the attachment setting advice?
