Delete the Files:
/includes/xml/cpnav_evbs_sstab.xml

after that (if still showing) rebuild the bitfield

And as I play with it on my test platform, to put it nicely, IT ROYALLY SUCKS.

That said, will this mod continue to work in 4.2 or should I take the above tab disappearance as reported as a no?

In any event, thanks for the work on this mod, I have enjoyed using it; it's far superior to what vBulletin is offering.

For giggles I tried installing this on my 4.2 test platform. It appears to install properly, the basic settings show under options, but the Tabs VbSoporte menu for editing tabs doesn't show up. I double checked to ensure I uploaded files in correct folders and I did. Ugh.

EDIT: I should have triple checked. I had one file in the wrong place (/includes vs /includes/xml). Menu IS now showing up. I'll report back with findings.

And finally, it seems to be working just fine in 4.2. Provided that some further testing is successful I'll definitely be continuing to use this mod going forward.

Maybe it's because your header templete still in vb 4.1.12 version, I don't see 4.2 header template but I', sure that now have many conditional or diferent code for their own tab manager

Still works fine for me in 4.2

Updated my site with it works like a charm

Excellent, HOWEVER can I make the tab that has a dropdown menu clickable so that it goes to a URL? Not the dropdown menu items, but the actual TAB?

Anyone know?

No, the tab cannot be made a link if it has dropdown menu items. I just tried it to make sure and it wouldn't let me.
