Blank after Login

Hi guys,
Recently noticed that Virtualmin GPL has stopped working – there is a blank screen with only the notification bar on the
right on the Authentic theme. Can’t recall any changes that was made prior to this happening, but we are using php55w
packages from webtatic repo instead of the official php packages. Also, we’re using mysql57-community package from
the mysql repos.


Thank you for your kind assistance.

Apologies, guys.

Found a possible solution here:
and here:

Will try out and revert if there are further issues.

Thanks again!

Traced it to an ipv6 loopback:

Modified /etc/hosts file as below (commented out the "::1"s): localhost.localdomain localhost localhost4.localdomain4 localhost4

The following lines are desirable for IPv6 capable hosts

#::1 localhost.localdomain localhost
#::1 localhost6.localdomain6 localhost6

I don’t know if that is your real problem since what you have done was to disable IPV6

You’re right Sir,
We found an issue with the Postfix maps.
Not sure how the ipv6 disabling solved that.

Yes I’m having that issue right now, And I was in the Process of Putting the Maps in and just basically copy/pasted the “?” suggestion from VM ad I have NO clue what goes there… I will try the Comment out and report back…

Ok, Commenting ::1 knocked out VM and the Site offline (Time-Out), I had to go in to and remove the edits I made In the Postfix Mapper and remove them, Puts me back to WHAT to put there… But at least it loads now… More searching…
