Hi everyone,

I have a small problem with my Sugar.

In detailed account view i'm trying to switch from "All" subpanel to "Collaboration" subpanel and i'm getting information that there were errors on page.

In details of problem I'm getting this information:

Line: 113
Position: 246
Error: No definition "SubpanelInitTabNames"
Code: 0


I'm running SugarCRM CE Version 5.5.0 (Build 6653) on MySQL. There's attachment witch error.

I'm getting this error in IE 7, IE 8 and FireFox.

Thanks in advance for any help.
