by mistake ,
i changed the directory and sub directories of the path /usr/share to the permissions 777
i type in the console
$chmod -R 777 /usr/share
but i made an iso backup before 4 days ,
my question is ,
if i copied the folder /usr/share from the old server which is before 4 days and paste it in my current server ,
should it fix the problem ???
or new errors may occurs ???
want to mention that firewall is not working after chanfing the permission of /usr/share to 777
