this step - not help
finally resolve problem - delete preference, remove ALL extension, install just parts
now it work, but I afraid install removed extension :-) and now have dilemma:
- re-install and agree with risk again has a problem
- rewrite some pages using WA, for example CSS menu in my old project build with Ajax CSS Menu (now extension removed, but if I need modify in feature?)
in any case - thanks for operative assistance!
