Description
I've created a new instance of XWiki 9.11.4 with PostgreSQL 9.6.3 and Chrome 65. Created and removed some pages and after some time my instance kept loading and I got the following error in the console:

I've created again the connection with PostgreSQL, from zero with no database and started to run some tests again. This time the error appeared when I clicked on Extensions from Administer Wiki.
Can't find a clear pattern on why this error keeps appearing, I get in randomly.
