Answer

It is known as state loss. You happen to commit a FragmentTransaction from AsyncTask. That is prohibited by the framework itself.

If you are okay with the possibility of state loss and behaviour unexpected by user, you could use

FragmentTransaction#commitAllowingStateLoss()

instead of

FragmentTransaction#commit()

Anyway, consider reading the link I provided, it is a very common situation.

Edit: Also, there is a workaround of your problem. But I guess, the consequences of this lead to a possible state loss, too. Nonetheless:

Declare a Handler in your Fragment:

private Handler handler = new Handler();

Then, in your onPostExecute(..) do this:

@Override
protected void onPostExecute(String result) {    
    progress.dismiss();
    Toast.makeText(getActivity().getApplicationContext(), result,
                Toast.LENGTH_LONG).show();

    handler.post(new Runnable() {
        @Override
        public void run() {
            hideKeybord(edt_txt);
            FragmentManager fm = getActivity().getSupportFragmentManager();
            FragmentTransaction fragmentTransaction = fm.beginTransaction();
            StoreProfileGridFragment fm2 = new StoreProfileGridFragment();
            fragmentTransaction.replace(R.id.relative_sendimage_send, fm2,
                "HELLO");
            fragmentTransaction.addToBackStack(null);
            fragmentTransaction.commit();            
        }
    });

    return;
}
