Error: could not load button JToolbarButtonPophelp

-- HikaShop version -- : 2.6.0
-- Joomla version -- : 3.4.5
-- Error-message(debug-mod must be tuned on) -- : could not load button JToolbarButtonPophelp ();

We were hacked!

I got the site back up and even was able to test the front-end and place an order and watch it go through successfully.

So why am I here? The back-end of hikashop is entirely broken.

I log in to the back-end and go to the Dashboard and everything is fine except... this error:

could not load button JToolbarButtonPophelp ();

And then I click on pretty much anything and I get a page that has the menu blown wide open with no styles... and nothing works.

I thought about deleting and re-installing hiksashop but we have hundreds of products that I do not wish to lose.

Thoughts on how I can fix this?

Thanks in advance for any help!

Looks like a log-out and log-in and let the T3 framework identify that the shop was behind... upgraded... now it is working fine.
