Sanjays Metal Halide Lighting database not working...

[Sahin]

Wasnt sure where to put this, but can someone let Sanjay or whoever maintains that part of the site know that it isnt working.

I tried on my Ipad and it wasnt working. Also tried just now on my laptop and I get the same message whever I try to plot the spectrums:

JpGraph Error: 25107Can't write to file "./tmp/ca0c327e1cb0053c1b699dd346bf25bf.png". Check that the process running PHP has enough permission.

Would be great to have this working again.

Many thanks.

Bump, can't seem to find the MH guide. Only the LED database comes up after I click on "Sanjay's Guide" from the main page. Any help would be greatly appreciated.
