Hower graph in 0.96a are not shown anymore

[Cosmin Neagu <cosmin.neagu@xxxxxxxxxxxx>]

Hello guys,

I was using php weathermap for a few days, i have one map copied from 
another machine, and it worked well, i mean, hower graph shown up, info 
url is working right.
I copied a second map, am that to worked one day, but this morning, no 
hower graph apear on links. Also i can see no errors in cacti log so i 
dont know where to look for posible problems and solutions. The strange 
thing is that Info Url works on some links, but on others it doesn't work.

Does anyone had this problem with v0.96a?
