cd /home/bareyour/public_html/social/periodic; /usr/local/bin/php -q cron.php
Looks as if it may not be right to me, is this in a live server? More likely to be something like...
cd /home/vhosts/bareyour.some.suffix/public_html/social/periodic; /usr/local/bin/php -q cron.php
Also /usr/local/bin/php may not be the right path to php. Could very likely be /usr/bin/php
IE - I removed "local".
Further more I have my server set up so that excluding the path entirely also works so try something like...
cd /home/vhosts/bareyour.some.suffix/public_html/social/periodic; php -q cron.php
If that doesn't work use a terminal to connect to your server. I use putty, it's very simple and efficient and free. http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
from your root directory (you may have to do cd.. a few times to get to root one logged in) enter the comands manually trying different variations...
#cd /home/vhosts/bareyour.some.suffix/public_html/social/periodic
Make sure you have actually changed to the periodic directory!
then try
#/usr/local/bin/php -q cron.php
then
#/usr/bin/php -q cron.php
then
php -q cron.php
if you get a very short pause and the command prompt comes back then that variation is correct and you should enter the cron job as per the command that worked. If you get an error message on all of them post the error message here.
Tip: to copy from putty use <ctrl> and <insert> and to paste into it use <shift> and <insert>
