admin.catalog.products.multimedia.savebeforeedit

I am using the version 4.60.0 ... when creating a new product, but before it is saved, when I scroll down and look at the Multimedia area, I see

admin.catalog.products.multimedia.savebeforeedit

After I save a new product, the text information above goes away, and the multimedia area looks as it seems that it should.

That's a language resource string name.  It's supposed to have a value like the messages used when you add other "children" entities to the product.  For example:

  You need to save the product attribute before you can add values for this page.

It's only referenced here
\Presentation\Nop.Web\Areas\Admin\Views\Product\_CreateOrUpdate.Multimedia.cshtml
@if (Model.Id > 0)
{
...}
else
{
...@T("Admin.Catalog.Products.Multimedia.SaveBeforeEdit")...
}

You can manually "Add a new record" in the language string resource, but this is something the nopC team needs to look into, because I don't see that resource in their demo either
https://admin-demo.nopcommerce.com/Admin/Language/Edit/1

However, I don't see how it would be used, since both uploading images or adding videos does seem to save them automatically.  (i.e., no need to, as per the typical  SaveBeforeEdit message: "save the product ....before you can add values for this page")

Do you always see it when you add/edit a product, or only when you make specific changes (i.e. add 'children')?

Hey, I came across this again (for nopCommerce 4.60.0 users). It happened this time when I went to Configuration/Settings/General settings/Localization and unchecked the following two options:

Load all locale resources on startup
Load all localized properties on startup

In the Log, a Warning was given with the following:

Resource string (admin.catalog.products.multimedia.savebeforeedit) is not found. Language ID = 1

I saw on github that the root problem has been handled. Again, this is really just for nopCommerce 4.60.0 users.
