IVR configuration problem

I have being trying to configure the IVR on the freePBX downloaded on my system it was giving problem. I can’t save any changes made to the IVR configuration form, it keep on reseting after save button is being click.

After selecting the SAVE button on the bottom, did you apply the changes by clicking on the top at the top of the page? This is necessary for almost any change in FreePbx.

I click save button but all the content of the extention input box (1,2,3,t,i) and other setting is always going off i.e. wiping and if i click on apply changes at the top of the page it doesn’t have any effect on it.
