I upgraded on of my site with the latest stable version of XOOPS and installed the wordpress module. Everything went fine but a couple hours later while I was writing articles in the wordpress module all jpg images located in folders with permissions set to 777 were deleted from the server. Not only the pictures in the XOOPS section but all other sections run by other softwares in the domain and subdomain were deleted.
Can this caused by the upgrade or the wordpress module or was I victim of a hacker?
