This is my first experience with CC5 so I downloaded Flexcrete to learn how to edit and add content. I started making changes then realized from tutorials and posts in the forums that I should make a copy of the packaged theme so I didn't lose my edits when the original packaged theme updates. I copied the package from the concrete/themes folder to the /themes folder with a new name (flexcrete_2), renamed all the flexcrete folders in the new folder to flexcrete_2, changed the info in the description.txt to the new name, and tried to rename the png file ( I never found flexcrete.png so I skipped this step). I made sure I cleared the cache also.

All of my old references to flexcrete are now flexcrete_2 in the new folder under /themes. When I went into the dashboard/themes there is no sign of my custom theme. Someone on the forum told me I needed to remove my old flexcrete theme before installing the new one and to change the controller.php to refer to the new name also. I did that to both the controller.php files I found in the new folder and subfolders and still no sign of my flexcrete_2 custom theme. So I thought maybe I needed to signout and then back in. Once I did that I can't login anymore so I am completely stuck.

There is no dashboard anymore and I get the following error:

An unexpected error occurred.

File not found. All themes need default.php and view.php files in them. Consult concrete5 documentation on how to create these files.
