"this.blank is not a function"

Bug
1

Being on the latest Github version, a user fails to save a new post with “An error occurred”.

In the log I found:

Uncaught TypeError: this.blank is not a function
Url: /discourse/controllers/composer
Line: 164
Column: 22
Window Location: http://entwicklergate.de/

Call stack:

Any idea how/whether I can fix it?

@eviltrout is this ember upgrade related ?

Do you have any plugins?

Thanks!

I’m only having the official tagging plug-in, IIRC. These are the plug-ins:

I’ve just updated to ‘ab80240’ with no improvement.

Although no more log entry, still no save possible. Generic error message:

Sorry, an error has occurred.

Are all users unable to save posts or just one? Did s/he refreshed his/her browser’s cache?

My forum is very low traffic. So it is only one user that experienced it.

Luckily it is the co-worker sitting at the other here in my office room :smile:

I’ll ask him…

Asked him. The error still persists.

It is a posting with 3 images, maybe this is the reason?

Also I manually enhanced the user’s trust level in the admin area from 0 to 4.

Identified problem.

Desired title “EF6 model first + Oracle.ManagedDataAccess.Client.EntitiyFramework” didn’t work.

Error: Entschuldige, es ist ein Fehler aufgetreten.

Changing title however to “EF6 model first” workes fine.
