I suggest to uninstall the product and then import the XML again.
Please note that this will delete all your old warnings etc.

I keep getting this error when i enable the warning system (when i try to reply to messgaes or post new ones)

Do you use RC3?

No RC 2 is that the problem?

Yes it is.

Ok thanks, looks like i'll have to upgrade then!!

Instead of having buttons or images for "Warn USER" & "View USERS Warnings" would I be able to use an image?

I believe this is a preconfigured option.

AWS Options > Manage Warning Options > Formatting Options > Text/Buttons

Then take the three preincluded iamges and make new ones and name them the same as the old ones and upload.

The only images included are closeOFF.gif, closeON.gif & warn.gif

I want to change Warn Ritch & View Warnings into images, not text or the buttons ?
