Configure AJAX User Interface error

I’ve got the problem that in Quotes text kept saying Undefied. So i followed the instruction to turnoff AJAX.
Didn’t work for me. Than i got back to the “Configure AJAX User Interface” page and got an error.

I can’t change it anymore.

Does someone have any tips?

Hi Alfred,

What is your server/mysql/php setup?

It may be permissions related.
