Main page suddenly missing right side bar and footer

Hi All,

I'm developing my site. Everything appeared to be working okay however, now, I have lost my right side bar and footer on the main page (possibly when I tried to change the location of the site on the server). If you go to any other pages the side bar and footer appear. My site is here:

https://www.infrasonic.com.au

Featured products and specials also do not appear on the main page (but do on all other pages).

I've tried replacing the "tpl_main_page.php" and "tpl_footer.php" in the includes/templates/my template/common folder without luck. I also recall this problem might have happened after I changed file permissions while tightening security as per the zen cart wiki recommendations - possibly that might have affected something?

Any suggestions?

Cheers

Start here:

Fixed! I re-installed entire backup of the store (not the SQL files, just the server ones via ftp).

Now working fine.

Cheers!

Epilogue:

I found out what the problem was; tightening permissions on the "include/languages/english/html_includes" folder and the "my_template" sub-folder. When I change them to 644 I loose the right and bottom banner boxes. But if I set them to 755 the formatting is fine. Note all files in these folders are set to 644.

So how should set the permissions for these folders?

755 for these folders:

Okay thanks for that advice.

The page you referenced seems to conflict with this one here (unless I'm mistaken):

Possibly this page needs updating?
