[smokeping-users] empty graphs

The rrd files seem to be getting updated properly, and the images are there; perhaps the paths are wrong?
But the images in /var/www/smokeping/... are all old, not updated, but those in /var/cache/smokeping/... are all updated.

I do see that the file: /usr/share/smokeping/www/javascript is missing (from the link in /var/www/smokeping/javascript)
	root at alpha:/usr/share/smokeping/www# ls
	cropper  images  prototype  scriptaculous  smokeping.fcgi.dist  smokeping-zoom.js

Not sure why, as I just did a reinstall of the whole package.

This is on Debian, and he latest version they supply is 2.6.11

Subject: empty graphs

I have had a smokeping running for years(!) on a small local Linux system - but something broke.

I started getting a BigLoss, and to fix it I had to delete a target in /etc/.../Targets. (It was down for a long time before I finally fixed it.)

Then it seems to run again (after restart), but I get no graphs; but instead empty boxes for each target where a graph should be. I did a remove and re-install, no effect.

Seems like the uninstall does not remove everything since it still had all of my Targets on the new startup.

I am not sure how to debug or remedy this, any hints or ideas?
