I did something major wrong and brought down our DEV site.  Here's what I did:

1.  I downloaded a copy of /modules/mod_rsitems.php to try to fix the gallery linking problem.
2.  I made a one line tweak to test the code:
Original Line:
    $RSG2Itemid = $RSG2Itemidobj[0]->id;
I added after that line:
   $RSG2Itemid = $RSG2Itemidobj[277]->id;
to see if I could force the ItemID in the URL (it was only a test!)
3.  I uploaded / overwrote the file ad refreshed the page.  I got this error:
We're sorry but the page you requested could not be found.

We have OpenSEF running but any page I try to go to is broken.

4. I reinstalled the backed-up copy and still keep getting the same error.
5. Thinking I could easily fix this problem, I uninstalled the rsitems module.  Still same errors.
6  I reinstalled the rsitems module and still get the smae errors, but now I have to recreate the 6 copies of the rsitems modules I had throughout my templates.

Please help!  What did I do?  I noticed that I can't access the Jevents calendar in the backend and in the frontend, I get a warning:

Events Calendar
This module needs the Events component

How did my little test break another component?

I figured out what was wrong and feel even dumber than before.  Somewhere after making my first or second FTP transfer, I must have clicked some button in the FTP program that renamed my components folder to httpdocs.  Once I changed my folder name back, almost everything works, except for my Jevents Calendar module, but I'm working on that now!  Sorry everyone for the false alarm!
