Title Tab Goes Blank When Selected

[Josh Rae]

I just had a new problem appear in my Sugar instance. We're running SugarCRM CE 6.0

Whenever I click on module title tab the module opens and the tab goes blank. All the other tabs are visible and I can still click the blank spot to reaccess the module I'm in. If I click on another title tab, the original tab will reappear and the one I just clicked will disappear. Very strange... In fact, the normal light blue toolbar that wraps around all of the tab titles is now gone completely (The tab titles themselves are still there). Last viewed and action toolbars are fine.

In the screenshot I'm attaching I'm currently in the "Home" module. As you can see, the word "home" has disappeared from the toolbar.

The most recent thing I've changed in our system is modifying the URL in the config.php file so that activity "invites" would send an email with the correct link. (not localhost/sugarcrm)

Thanks for any help provided.

This is a problem with file access. In your Classic theme the style definition for the tabs refer to a graphic file: ../../../../index.php?entryPoint=getImage&themeName=Sugar5&ima geName=currentTab.gif. If this file is not accessible you get the effect you described.

This is the style definition responsible for displaying the current tab. Disabling the "background-image"-setting leads to blank tab title:

#moduleList ul li span.currentTabLeft, #moduleList ul li span.currentTabRight, #moduleList ul li span.currentTab {
background-image:url(../../../../index.php?entryPoint=getImage&themeName=Sugar5&ima geName=currentTab.gif);
background-repeat:no-repeat;
border-bottom-color:#4E8CCF;
}
