Your mails are blocked with the error message “554 Denied [CS] [*.mxlogic.net] (Mode: normal) (in reply to end of DATA command)”

What does it mean?

The mail was rejected by Mxlogic / Mcafee because of the content of the message.

Try using different message

If you are facing issues with rvsitebuilder on cpanel server with error

“Fatal error: Cannot make static method SGL_FrontController::run() non static in class RVSWebInit in”

Run the below commands to fix it

perl /usr/local/cpanel/whostmgr/docroot/cgi/rvsitebuilderinstaller/autoinstaller.cgi –force=rvseagullmod

Then run update RVSitebuilder again.
perl /usr/local/cpanel/whostmgr/docroot/cgi/rvsitebuilderinstaller/autoinstaller.cgi –force=rvsitebuilder

Now  republish the website, the error will be fixed

SSH to server and use the below steps

Check active volume first using

[root@load ~]# lvscan
ACTIVE            ‘/dev/vg_load/lv_root’ [50.00 GiB] inherit
ACTIVE            ‘/dev/vg_load/lv_home’ [53.80 GiB] inherit
ACTIVE            ‘/dev/vg_load/lv_swap’ [7.50 GiB] inherit

Say you want to remove the volume /dev/vg_load/lv_home

Type the below command

[root@load ~]# lvremove /dev/vg_load/lv_home
Do you really want to remove active logical volume lv_home? [y/n]: y
Logical volume “lv_home” successfully removed

Now the logical volume is deleted

which you can confirm using

[root@load ~]# lvscan
ACTIVE            ‘/dev/vg_load/lv_root’ [50.00 GiB] inherit
ACTIVE            ‘/dev/vg_load/lv_swap’ [7.50 GiB] inherit
