Hi guys,

This error just happens in server.conf

What do you have around line 56 of /etc/httpd/conf/plesk.conf.d/server.conf

Hi Mark,

Exactly this line : Header add X-Powered-By

in

<IfModule mod_headers.c>
Header add X-Powered-By
</IfModule>

I think i found the problem

Before i edited the server.php template and i removed PleskLin word form it and it was the reason for error, now i changed it back to Header add X-Powered-By PleskLin and problem has been fixed.

َanyway thanks in advance Mark for followup and help
