Widgets Ghosts in dashboard (2.2.6-release)

aniodon

Hello everyone

I'm facing something strange about the dashboard and widgets.
I think, but cannot be sure, it happened after the pfblockerng package installation

On the dashboard:

I add the "System information" Widget –> I have one "System information" on my dashboard
I click the "Save settings" button --> there is now Three "system information" on the dashboard

from now, i can only close one of the three "System info" widgets

If i close this one, there is still two widgets, but if i hit "save" with those two widgets displayed, they disappear.

It seems i can close the two widgets left if i move them to another column, but that do not change anything they still reappear after adding and saving.

I tried to clean the dashboard, problem comes everytime i add this widget.

Some informations :

i'm on 2.2.6-release
on any browsers
problem with "system information", pfblockerNG, or Snort widgets at least
tested with the ng-fs (1 to 3 columns) and ng themes

Is there any way to "clean" the dashboard settings?
any other idea ?

thanks in advance
