Thank you for your feedback.
We don't have the avatar option added yet into the site. But members have the freedom to choose a profile picture of their own liking or if you want to see a uniform profile picture, you can choose to go to My Center > edit profile > administrator edits and override profile picture for all the members.
For uploading of files, you can utilize FTP or the Download Center.
Can you please help with a screenshot of the error when using FTP and send to [email protected]
so we can investigate and work on a fix?
Thank you for taking the time.
