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

regards
