On a localhost environment, when I try to create a new node, I get this message:

The connection was reset.

There is some issue with css, cache and/or registry since when I disable the css aggregation it works for the next node and it stops for the next node creating. In order to work again for a new node it needs enabling the Css aggregation and so on.

Also when I clear caches I get this kind of messages:

The following module has moved within the file system: views_test. In order to fix this, clear caches or put the module back in its original location. For more [warning] information, see the documentation page. bootstrap.inc:1128

Any suggestions? Thanks.
