Your version of Cacti is too low for the plugin. You need to find an older version of the plugin.

My version of cacti is 1.2.2 and the webseer plugin is 3.0

OK, apologies, the file path led to some confusion: /cacti/cacti-0.8.8b/plugins/webseer

[Lalbee99]

Sorry it was my original cacti install version. I haven't gotten around to modifying a MySQL backup with a generic path (/cacti) and performing a restore after the upgrade. It is on my to do list.

Download the latest development version. Your line numbers didn't line up with what we have but I have made a guess. If it cures your problem I'll update the version details accordingly.

Good to go no more errors. Good work !
