No output on elgantt-open on test file

[PatrickLohan]

Hi!

I have tried the test file and there's only a blank buffer (more precisely 2 blank rows of 20 columns width. First one same colour as theme background, second row a lighter shade).

The messages buffer shows "Error during redisplay: (eval (elgantt--header-line-formatter)) signaled (wrong-type-argument characterp nil) [2 times]". I'm guessing this is the problem. Can anyone help?

Hi, As explained on https://github.com/legalnonsense/elgantt/issues/16 I've added the following line in the init.el and it works: (setq elgantt-start-date "2020-01-01")
