Quota error (device dm-4): find_block_dqentry: Quota for id 107 referenced but not present

I have problem with my server. For server configuration I followed http://www.howtoforge.com/perfect-server-ubuntu-12.04-lts-apache2-bind-dovecot-ispconfig-3-p5

My screen is flashing every 20 seconds with

[ 545.828437] Quota error (device dm-4): find_block_dqentry: Quota for id 107 referenced but not present
[ 545.829017] Quota error (device dm-4): qtree_read_dquot: Can't read quota structure for id 107

( I also did photos because cant find thease errors in logs).

My fstab:

proc            /proc           proc    nodev,noexec,nosuid 0       0
/dev/mapper/prasytojas--vg-root /               ext4    errors=remount-ro,usrjquota=quota.user,grpjquota=quota.group,jqfmt=vfsv0 0       1

/var/log/ispconfig/httpd/1d.lt /var/www/clients/client1/web5/log    none    bind,nobootwait    0 0

How can I fix this?

Try removing the quotas:

sudo cp /etc/fstab /etc/fstab.backup

to make a backup of your current fstab file. Then edit fstab and remove the ,usrjquota=quota.user,grpjquota=quota.group,jqfmt=vfsv portion.

sudo mount -a

to reload the fstab entries.

Sadly there is no explanation in the HowTo you used describing the intent or application of enabling quotas. It may be covered in the ISPConfig documentation. If your services are running normally, there's usually little need to enable them except in scenarios where storage capacity is limited based on the number of users utilizing those assets.
