Being on the latest Github version, a user fails to save a new post with “An error occurred”.
In the log I found:
```

Any idea how/whether I can fix it?

@eviltrout is this ember upgrade related ?
Do you have any plugins?

We just picked up one of these in our logs as well.

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 😄
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.
