 * I just inherited this blog from someone else and unfortunately have no way to
   contact them. The theme was updated directly as opposed to using a child theme.
   So, I just created a copy of the parent theme folder, renamed it “hybrid-child”
   added the style.css header Theme Name and Template Name.
 * **Now when I try to update to Hybrid 0.3 to 1.2 I get a the following error on
   my admin page:**
    Server Error The website encountered an error while retrieving
   [http://50.87.191.241/blog/wp-admin/update-core.php](http://50.87.191.241/blog/wp-admin/update-core.php).
   It may be down for maintenance or configured incorrectly. Error code: 500
 * **and the following error when visiting the site: **
    Server Error The website
   encountered an error while retrieving [http://50.87.191.241/blog/](http://50.87.191.241/blog/).
   It may be down for maintenance or configured incorrectly. Error code: 500
 * Should I not have copied all of the parent files? When I just used the stylesheet
   in the child-theme many elements on the page where broken.

 * So it looks like I may not get any help on this issue and I need to resolve it
   soon so I’m coming up with plan-b.
 * I think there are some files in the child theme folder that are conflicting with
   the update. I would now like to download Hybrid version 0.3.3 and compare all
   of the files in my child theme with the original files. The only problem is that
   I cannot find a version of 0.3.3 anywhere? Can anybody point me to this old version
   or have it locally by chance?

 * No, copying the functions.php file usually crashes a site :/ .
 * See: [http://codex.wordpress.org/Child_Themes](http://codex.wordpress.org/Child_Themes)
 * So moving changes to a child theme would be the best solution. Old versions are
   here:

 * Thank you! This is quite helpful.
 * It seems whoever created the site modified the functions.php file and many others.
   They also reorganized the directory structure a bit. Looks like I have my work
   cut out for me.

 * Oh ugh, well, just be sure to make a good full backup before you start and keep
   working copies of your files as you go alone…that usually gives you a good fall
   back.
