According to the last changes, to save your previous changes, we suggest you to perform the following actions: (1.5 version has new directory structure).
Please login to your FTP and backup user images located at wj-autodealer/framework/usr_dat directorya. Download this directory, and after that – start updating the theme.
After theme installation you must upload directories “car”, and “user” from downloaded “usr_data” to “wp-content/uploads/at_usr_data”. In future this will give you guarantee that after another update and even theme removal, your images will be stored in the safe place.
