There's rather weird behavior of Gravity Forms on our website. When form submit button is pushed, spinning arrow shows for second and then the whole page html is inserted in the form end. Form is not submitted obviously.
I tried disabling plugins, unload all scripts, I seem tried everything - nothing helps. The only page where form works is homepage. All pages accoss website share same scripts. And I don't receive any script errors either.
Maybe this is something wrong with wordpress install? Today upgraded to 3.5.1.
Will greatly appreciate any help or ideas! I am in complete despair :(
