Cannot save options in 'Settings/Personal Fundraiser' page

Hi John

This is actually one of the easier fundraising plugins I’ve tried to set up, and I’ve tried a lot of them over the last 3 months or more. I can’t tell you how much relief this is for a bootstrapped startup.

.. but I’m stuck and wonder if I may ask for your advice please.

*I’m using WordPress 3.8.1 running Builder Child theme.
*I’ve followed the steps (I have one cause which has one campaign, paypal setup done, separate campaign page for the Donate button).
* my permalink setting is Post name.

I’m unable to save any changes to the options in ‘Settings/Personal Fundraiser’ page. I cannot save my ‘Donate Button Code’, ‘Payment Data Transfer Token’ and ‘Personal Fundraiser Fields’.

After I click save, the next page is blank (but has the header and footer), and the tab says “Nothing for Wp-Admin Options Php. I go to the ‘Settings/Personal Fundraiser’ page again but no changes were saved.

Can I ask for your advice .. what I am doing wrong?
