Unable to save new elements in backend after upgrade

[aksmith]

Hello:
Just upgraded to the latest via github (3.0.6.3) in a Joomla 2.5.7 site.
I am unable to use "Save", "Save & Close" or "Save & New" in the backend for existing or new elements. Furthermore, when I try to create a new element, it is assigned an id of "0" (= no id).
Thanks in advance for your help -
Alan
ps: tried watching video tutorial on debugging upgrade, but the video froze after the first 30 secs...

Never mind - found relevant thread on community board - clearing browser cache takes care of this.
Sheepishly,
