You installed Gitlab from a Bitnami installer or on Amazon Web Services Marketplace
I ran into this issue when I installed Gitlab from the Bitnami-flavored AWS ec2 image:
Everytime I would click link in Firefox the page would show up entirely blank.
The html is sent perfectly as confirmed with Firebug and on a refresh the page would show up as expected.
Works fine in chrome.. Hmm. Google Page Speed? Yep.
To disable the page speed mod, edit the config file:
/opt/bitnami/apache2/conf/pagespeed.conf and change the value:
After changing this, don’t forget to restart Apache.
$ sudo /opt/bitnami/ctlscript.sh restart apache
Or if you’re not using a BitNami machine:
$ sudo service apache2 restart
Great job to the Gitlab team & Bitnami on the collaboration!
