Error: Gantt to pdf (500 error)


#1

Gantt to pdf returns 500 error suddenly.
It worked until last week with the same coding.

Error message.

Internal server error. Error: Gantt to pdf. Error: [electron] Fontconfig warning: “/etc/fonts/fonts.conf”, line 100: unknown element “blank”

It there any system trouble currently or any update in a few days?
