upgraded to 2.2.6 / control panel

I had several hacks showing in the navbar in the control panel. They are now gone after upgading to 2.2.6.
Is there a quick fix or do I have to add them again one by one.... the rest of the hacks seem to be OK.

You will need to re-add them manually, when you upgraded, you replaced the old files with the new files.

Thanks - I just did that for 5 hacks and it's back to normal!.... only Firefly's query hack is left...
