Hi Chris,

Did you just recently install Header Tabs? If not, do you know what might have caused this change in behavior?

Also, could you please temporarily add the following to LocalSettings.php:

$wgResourceLoaderDebug = true;

...and see if that leads to a better error message?

I'm getting the following exception from HeaderTabs (1.0.2 (29d694f)), even on pages without header tabs. I'm on 1.26wmf18 and even after disabling other potentially conflicting extensions (Echo) I'm still getting the message. Any insight would be appreciated.
