Im just simple update Sydney theme to 1.35 and after the process, i found strange things in wordpress, e.g. plugins didn’t deleteted, and i get white screen whene i want see my page. I logged out and whene i want to loggin again white screen. Via FTP I tried to rename the plugins folder to check that is a plugin conflict or not, but nothing happend. After that i tried the same whit the themes folder, and the wp admin panel appers correctly. Now i deleted the sydney theme and setup the 1.30 version and everything is ok.
Should I update the theme, or the older version will work correct too?
