Configuration Problem - Forbidden Access to certain areas?

[Jeff_Mash]

Hi DrByte and Team! Hopefully this is an easy solution. I know that it's something I did, but I can't narrow it down.

When I go to the "Install SQL Patch" page, it loads fine. But if I try to run a script (or even by hitting the "Send" button with no SQL input), I get a blank window with the same error in my Apache log:

[Tue Mar 31 17:04:21 2015] [error] [client 76.127.117.11] client denied by server configuration: /home/mjmmagic/public_html/store/admin/includes/languages/english/images, referer: https://www.mjmmagic.com/store/admin/sqlpatch.php

Now, I have no idea why it's referencing the "images" directory in the ADMIN path, since the following path doesn't exist:
/home/mjmmagic/public_html/store/admin/includes/languages/english/images

But still, I am not sure if that is the problem or not.

The same thing happens when I try to do other things too. For example, I just installed the SitemapXML module. That loads fine and creates the sitemaps.....but when the popup window runs the module, it just stays white, and that too throws the following Apache error:

[Tue Mar 31 17:05:58 2015] [error] [client 76.127.117.11] client denied by server configuration: /home/mjmmagic/public_html/store/admin/includes/languages/english/images, referer: https://www.mjmmagic.com/store/admin/sitemapxml.php

As you can see, it's the SAME ERROR even though we are talking about two different things. So this shows that it's some kind of permission or misconfiguration on my end.

Any ideas on how to resolve that, or what I should look for?

(For the record, I just upgraded from 1.5.1 to 1.5.4 in case that helps explain anything).
