update to 4.0.0 gives only one column results

Could you eventually get me a screenshot of your view settings and of the result, since I don't really figure out the result you have here.

The configurations now requires explicitely the unit for columns for instance.
Also by default, there is a new option (not the last one, just before) to force elements widh to column size.

It is a pity there is no auto conversion, nor documentation for this change, nor a warning. So I have to update a lot of views by hand. Like a lot of other people.

If you run /update.php, you should have got a warning telling to check your configuration.
On after1.jpg I can see the sizes for columns does not follow the "description" below.
If you save those settings, it should triger an "error" on the setting form because "250" on the column width do not have a unit.

Thanks. I works for me.

Thank you for explaining this - this was the missing setting for us - did we ignore an upgrade warning that this was required then (can't see one)
