Profile pictures disappeared

Hi, recently I have uploaded around 118 profile pictures each individually onto gibbon and they seem to have disappeared after a while. When I go to edit a profile the User photo appears to have no files uploaded. Would you be able to explain what happened? My password also seemed to have reset itself at the same time. I hope I haven’t just wasted my time.

Many thanks

Might be something that happened with your database, since passwords have changed as well
try to restore a backup if you have

Thanks for a reply. Would you be able to help me figure out where are the pictures stored in the database? Last time I’ve uploaded them one by one. It would be easier to upload them in one go using Import From File feature. In “DataStructure-usersBasic” there is a column “UserPhoto”. I assume it takes links to the databse?
