Search box security token error

[imager]

Can anyone help me solve this problem with our board? If I use the drop down search box from the nav bar, I get a security token error. Please see attached screen grabs.

Thanks,

this is usually something to do with installed hacks or addon, i would disable all and try again see if you get that error.

Or it may be that the custom style was not properly adapted when the security tokens were introduced. Do a search for security token error on here, IIRC there's a sticky around re this topic.
