Reboot when trying to Upload

Hello ! I recently discovered your work and followed your steps to install that pretty interface on my 2 printers : A FB Ghost 4S and the other with an MKS Robin Pro and Mks Wifi module. It worked 2 or 3 times on the Ghost but now I can only monitor data on the two printers. When I try to upload something the board reboot and web interface takes some time to come back .. Do you think I have made something wrong ? UPDATE : Apparently it's the lenght of the gcode file names that were too long (40 characters), no problems with short ones
