Wxsim 3in1 script

Hello,

My old weather computer was crashing a lot. I set up a new system and configured WXSIM the same (I think) as my old computer.

Things that are not going in 3in1 is the top graph, hour by hour, etc. and I believe these come from lastret.txt

I have not touched anything on the web server
Everything worked fine before the new computer
lastret.txt is uploading

Obviously, I have done or not done something in my configuring of WXSIM / WRET but I cannot see anything.

Any ideas what may be wrong?

Thanks

Gary
