Is this a permission problem? Can you delete the artisan cache, the 
storage/framework/cache/data directory + reset the permissions on the 
storage/framework/cache and see if that works?

# ./artisan config:clear
# ./artisan cache:clear
# rm -rf /srv/ixpmanager/storage/framework/cache/data
# chown www-data:www-data /srv/ixpmanager/storage/framework/cache
# chmod 775 /srv/ixpmanager/storage/framework/cache

This might be a Chrome quirk. Can you try on another browser and report 
if that works?  If it does, we'll file a GH issue to fix it.
