Hi. I wanted to change the server and made backup database sql. I moved the files by ftp as always. And it turned out that changed the main categories in the template Tatiana on the original. Why? Now I have to adjust all over again! Shit!

Category settings are stored by osclass itself, not by theme.
Category images are stored in theme folder and if they are moved with other files and same database settings, those will be shown as on old side.
