I am starting with these commands

yum install mod_dav_svn mod_fcgid mod_perl mod_ssl php virtualmin-base

or

yum install php55w php55w-opcache php55w-common php55w-mysql php55-mbstring

I am getting the same error ,

now my site still has all the files but not able to reinstall apatche in virtualmin ,any advice or help ,??
