Help with lcdproc after last update

Hi, firstly sorry for my english, (I’m trying to improve it). I have had a problem after last update. I have a Rpi 1 model b with an i2c 4x20 lcd. It has been working properly until last update. I have tried to uninstall and reinstall lcdproc and addon xbmc lcdproc, but the problem hasn’t been fixed. Even, after install addon lcdproc xbmc, the backlight turn off. I have to switch off and disconect the powercord and reconnect it in order to get the backlight.

I like a lot my lcd… and i’m lost…
Can anyone helpme?
