[RESOLU] Add a new field in joomla 3.x

Hello,
When adding a new field, if I change the type-specific properties do not load.

If I do not change the field type by default, it is possible to create a new one.
Regards.

Hello

i don't have this behavior, can you upgrade to r1754?

also i you use firebug and go into network tab, and then try to change field type,

then the SERVER response will be visible there and thus you could copy paste the response (= error) here

This is the version that is installed r1754.
Here is the return of firebug:

Hello,

-- TAB "response" should be empty OR it should have a PHP error message

e.g. function call on a non-object

please enable error reporting of joomla to "Simple" and retry , does response TAB have some text?
