Hi,

A single-server install of SP 2019 (with db's in other server). No customization. Patch status:

On a publishing page, edit mode gets a Javascript error and cannot be edited:

When a new group site is created and permissions shall be added, also Javascript error and users cannot be looked up in user field:

Answer 1

Hi @Matz Höög ,

I installed the same Swiden Language Pack and the latest CU Update like this:

And tested in the publishing page edit mode, it's working as expected in FireFox, no JavaScript error in Console:

Also works in sub site permssion set page when resolve user in People Picker:

In the first capture in the original question, I see the ribbon is not loading compeletly, I suggest you could try to clean browser cache and try again to see if it works.

Also try in other site collection to see if the issue still exists.

If still the same issue, I suggest to check the ULS log for details.

Thanks
Best Regards

Answer 2

As can be seen in the second picture I posted, the Javascript error tells that a function is undefined "MSOLayout_SetupLayoutFlags". On the row above it says that the Javascript file ie55sup.js could not be loaded.

The Javascript function "MSOLayout_SetupLayoutFlags" exists in that file. If I manually tries to download that file in Firefox, /_layouts/15/ie55up.js, Firefox complains about a coding error of the content. Other Javascript-files can be downloaded.

Is this file updated by any patch? On the server it is updated 01/24/2021.

Can I get a copy of that file from your installation?

Answer 3

The Js file in my environment also modified at 01/24/2021:

I will upload this file as attachment as .txt file, you can rename to .js, please check:

74630-ie55up.txt

Thanks
Best Regards

Answer 4

Ok, that file worked!

I ran a "comp" with the two files and it said it was the same, but exchanged the original with yours anyway and it works. Strange...

What I can see in Notepad++, the encoding is the same also.

Could you please supply "entityeditor.js" also (same error with this)?

Thanks!
