can anyone help me on this one?

3

Provide more information. What versions of Openfire and plugin are used. Was it working ok before and when it started to show this error.

4

i just freshly installed the openfire 3.9.3 i recently installed monitoring.jar and after that the error comes up under plugin tab.

my main goal is to archieve the conversation of the users. but after installing the monitoring.jar ive got that error and no archiving tab on server panel.

5

the tab that i have under server is SERVER MANAGER, SERVER SETTINGS, MEDIA SERVICES.

6

What version of plugin have you installed? Why do you use 3.9.3 version of Openfire?

7

monitoring 1.5.7 … i just installed that version of openfire thats the first file that i saw. Maybe thats my bad for not researching furthermore… Do you have any suggestion?\

8

i hope you can help me on this wmatter

9

Please help yourself here and use version 4.2.1 of Openfire, then report any errors you see.

10

1.5.7 requires at least 4.1.0 version of Openfire. Do as akrherz suggested, use Openfire 4.2.1. It is the version available on the Downloads page.

11

so i will fresh install the openfire 4.2.1 under ubuntu server?

If you haven’t started changing configuration and adding users then starting fresh should be better.
