This is another thing that changed in 7 LTS: in TCA and flexforms the 
select boxes need to have a render type defined [1]. In previous 
versions it was attempted to conclude from the other settings how it 
should be rendered, but this didn't always produced the result that was 
wanted by the programmer.

In your case the file flexform_ds.xml in the root of jfmulticontent 
needs to be edited. There are 28 select fields in it.
If you change

<type>select</type>

into

<type>select</type>
<renderType>selectSingle</renderType>

this error should go away.

It could be that this can be solved -- as the error message says -- by 
running the database compare tool in the Install Tool (Important Actions 
page).

I just had a better look at jfmulticontent and there are some things 
that were already deprecated in 6.2 and dropped in 7 LTS. It could be 
that a programmer needs to replace some code here and there.

Another thing is the TS constant useStoragePidOnly. This makes the code 
use the General Record Storage Page only; that is a thing of the past, 
so you really need to set that constant to 0.
