Make a copy of your theme that your edited located here.

/public_html/concrete/themes/greek_yogurt

Upload it to

/public_html/themes/

Now you can update Concrete5 without worries and your changes will remain intact.

Thanks for the quick reply. I don't seem to have greek_yogurt in that directory. I do have a "default" folder. I've attached an image from my FileZilla. Have a look. Thanks so much!

Also, I did follow the steps of copying the default folder over to the public_html/themes folder to try it. I can't quite explain what happens (everything goes haywire) but you can have a look if you have the time:http://www.elkhartcountyhistory.org/about/...

I applied the New Theme to the about page. To see what I'd look it to look like you can go to the main page: elkhartcountyhistory.org

Any ideas on what I'm doing wrong?

If that is the theme you have activated and made edits to, then copy "default" to the root /themes directory and your all set.

Did you copy it or just move it?

Also there should not be a need to activate a new theme.

Putting the default theme in the root /themes directory simply overrides the styles to the default theme that you already have activated.

You may want to put the default theme back to its original state in concrete/themes/

Then have your edited version in /themes

This is good news. So there is no need to activate or install or switch my design of an already finished page?

To answer your other question, I copied it (rather than moved it). So I'm reading you correctly that whatever is in my root/themes is the theme that my pages are actually using? I can go ahead and update?

Again, your help is greatly appreciated.

That's correct. If you have copied your edited theme to your root /themes directory you are safe to update.

Okay. Not so good news. I'm not sure what happened and any help would again be greatly appreciated. I followed the above steps and updated the site. I backed it using concrete5 and by downloading all the site files from the ftp site.

The site is now broken in that I cannot access the site or dashboard etc...http://www.elkhartcountyhistory.org... is the site. The error message reads:

Warning: require(/home/m1schuld/elkhartcountyhistory.org/updates/concrete5.4.2.2/concrete/dispatcher.php) [function.require]: failed to open stream: No such file or directory in /home/m1schuld/elkhartcountyhistory.org/concrete/startup/updated_core_check.php on line 5

Fatal error: require() [function.require]: Failed opening required '/home/m1schuld/elkhartcountyhistory.org/updates/concrete5.4.2.2/concrete/dispatcher.php' (include_path='.:/usr/local/lib/php:/usr/local/php5/lib/pear') in /home/m1schuld/elkhartcountyhistory.org/concrete/startup/updated_core_check.php on line 5

Any ideas on what I've screwed up?

I just restored via dreamhost, so the link may show a working site by tomorrow, but I'm still not using an updated Concrete5

These errors would not have anything to do with copying your theme to the root themes directory.

You said you do have a back up of the site?

I do have a backup, but it is on my work computer and I am at home tonight.

Dreamhost didn't have any backups stored.

Any idea what happened? It happened immediately following my attempt to update Concrete5 to to 5.4.2.2

I've returned the site to functionality following these steps:http://www.concrete5.org/community/forums/customizing_c5/help-my-si...

But I'm still running 5.4.1.1

I sent you a PM.
