Just for reference, maybe somebody can find some use for this.

I installed Cacti, I added a few graphs, but I couldn’t see the first page of graphs in the graph view. I could click on the graphs and I would see all graphs, just not the first page.

After searching for problems I found the following line in my
`/var/log/apache2/error.log`

log file.

```
ERROR: I don't understand ':15:00 To 2011/03/09 10:15:00\c' \
in command: 'COMMENT:From 2011/03/09 09:15:00 To 2011/03/09 \
10:15:00\c'.
```

This problem can be fixed by choosing the right version of RRDtool in your
cacti Settings. So change **Settings** > **RRDTool Utility Version** to
‘RRDTool 1.2.x’.

Now the graphs will be shown.
