I keep getting the following errors when I try and edit the \App_GlobalResources\GlobalResources.resx file via the Language Editor.

The first one is

A File Operation Failed. Please Check Resource File Permissions So Files Can Be Edited.

I think this is due to the files/folder having read only access. I think this a hangover from the recent upgrade I carried out (4.9.0 --> 4.9.3) and I am looking at fixing this now.

The second error however looks far more serious as I keep getting this:

The error happens almost instantly with no sign of the browser/portal hanging. The rest of the portal appears to be working fine.

Does anyone have any ideas as to what could be suddenly causing this?

1. The App_GlobalResources folder has the correct permissions and all the files in the folder are NOT read only, but I am still getting the first error.

Update: Just noticed that although all the files in the App_GlobalResources folder are marked as NOT read only, the actual folder itself is marked as Read-Only. I have tried a few times to change this, but it alwyas seems to resort back to being read-only????????

2. I will check the necessary resource file to see if it is valid XML.

OK can someone please explain how the GlobalResources.resx files work?

1. In my development portal I used the Language Editor to change the text for the Admin.String. I clicked on Update and all appeared to have worked OK.
2. When I check the App_GlobalResources folder, I find that the GlobalResources.resx file has not changed, but there is a new file called GlobalResources.Portal-0.resx which contains my change.  OK I get that, as my portal is portal 0 and a new file is created that is portal independent - a good idea.
3. However I then logged out of my portal, then signed in again. I went to the Language editor to check the text for my Admin.String. What I saw though was the contents of the GlobalResources.resx file NOT the GlobalResources.Portal-0.resx contents. Why is this?
4. Anyway, I reapplied my change to the Admin.String and clicked on update and guess what, I got the error:  A File Operation Failed. Please Check Resource File Permissions So Files Can Be Edited.

So can someone please explain how this is supposed to work?

Did I miss a trick when I went into the Language editor for the second time - I can't see any option to select the portal-0 file?

Is this editor a once only chance? That surely cannot be correct?

Have I stumbled upon a bug in DNN? Surely I can't be the first person to edit this file more than once?

Is it a bug in the one of the latest releases (4.9.1, 4.9.2, 4.9.3) ? I am sure it worked OK in v4.9.0 - we only upgraded to 4.9.3 a week ago.
