Could be a timing problem or something with access rights. Normally I
would tell you to set "14all*GraphErrorsToBrowser" but:

this option requires the GD perl module which requires libgd. (If you
have GD installed than there might be a bug in 14all)

A quick hack to get the real error message: Add the line

   print STDERR scalar(localtime),"[14all] $errstr\n";

to 14all.cgi at line 440, i.e. just before the line

   if (yesorno($config{'14all*grapherrorstobrowser'})) {

and you will get the error message in your web servers error log.
