TypeError: sidebarPos is undefined

I am getting exactly the same error, except it only occurs on pages with BBPress on them.

Firefox gives the error as:

Uncaught TypeError: Cannot read property 'top' of undefined
    at belowEntryMetaClass (global.js?ver=1.0:124)
    at global.js?ver=1.0:240
belowEntryMetaClass @ global.js?ver=1.0:124
(anonymous) @ global.js?ver=1.0:240

I made a disgustingly bad bodge to get rid of the problem!

Around line 124 it reads:

sidebarPos       = $sidebar.offset();
sidebarPosBottom = sidebarPos.top + ( $sidebar.height() + 28 );

I just added a check. It’s not tested fully but it appears to work on my site – but there could easily be problems down the line with updates and other issues.

sidebarPos       = $sidebar.offset();
if ( sidebarPos === undefined )
	sidebarPosBottom = ( $sidebar.height() + 28 );
else
	sidebarPosBottom = sidebarPos.top + ( $sidebar.height() + 28 );

But this is something that the theme coders need to sort out and I take no responsibility for it! ??

I also have this issue when I make a child theme and have the side bar turned off.

@arathra This is just what I needed, thank you. It is ridiculous that this is necessary.

I could literally give you a limb right now I’m so ecstatic I found your code. I’ve been wracking my brain for a client trying to get rid of this error and this finally worked. Thank you thank you thank you!

A limb! Now that’s too generous. Make it a beer and we’d be quits ??

If you put an empty text widget (no title, nothing) in an empty sidebar, the problem goes away.
