I created many accounts in my jira software.
The upload user avator functions well for all accounts at first. But after one account tried to upload a big BMP file as his avator and failed, he can't do it good anymore. Anytime he trys to upload a user avator in any size and any format, the page prompts "Cannot attach file xxxx.jpg: Unknown server error". No detailed errors can be found in log file expect a 403 error. At same time, the other accounts can do it well still.
What happend? How to fix this problem?
