I solved the problem.
I change this code on row 299/306 of file sam-admin-edit-item.js:
onSubmit:function (file, ext) {
if (!(ext && /^(jpg|png|jpeg|gif|swf)$/.test(ext))) {
status.text(samStrs.status);
return false;
}
loadImg.show();
status.text(samStrs.uploading);
return false;
},
with this
onSubmit:function (file, ext) {
if (!(ext && /^(jpg|png|jpeg|gif|swf)$/.test(ext))) {
status.text(samStrs.status);
return false;
}
loadImg.show();
status.text(samStrs.uploading);
},
I have simply removed the 2nd return false
