Files should be 644
Folders should be 755

Please review the Security Checklist http://docs.joomla.org/Category:Security_Checklist
for more information.

in your web root folder:

find -type d -exec chmod 755 {} \;

and for files replace the d with f and the 755 with 644 and you are done

This can also be run from a shell prompt using putty if you have shell access for your account. some do and some don't have this access. Some hosts change the find command to something else so their find command would be something to the effect of abcfind instead of just find. Ask support if you are not sure what the command is for their servers.

You can also ask your hosts support to do this permission change for you and they will run the commands.

Hi

I can not do this from my Web Panel

If I do it from FileZilla, after I'll do problems running joomla? IO have seen that Filezilla have option to apply right to files & folders, only files or only folders...

I have a explorer joomla component (extplorer) but I havent seen this option

If nothing else works, upload this as permfix.php:

Code:

<?php
echo shell_exec( 'find -type d -exec chmod 755 {}\;' );
echo shell_exec( 'find -type f -exec chmod 644 {}\;' );
?>

and visit permfix.php in your browser... maybe you'll luck out and shell_exec isn't disabled...

Hi

I've tried but it displays error:

Warning: shell_exec() has been disabled for security reasons in /usr/home/xxxxxxxxxxxxxxxxxxxxxx.es/web/permfix.php

I have read on other forums that is not good idea changes right from WebHosting Panel or FTP Client because it can happen problems. That the most correct thing is to do it from own joomla site, but how? I cannot go folder for folder

regards

Okay, that was just a shot to see if that would work. I would recommend contacting your host to either change them for you or allow you ssh access.
