I was in the process of creating a child theme and I used the plugin One Click Child Theme. The child theme contained the content-image.php, content-video.php, and content.php files that were almost the exact copies of the parent theme files except for a few minor changes (space added inside a parameter, period deleted), plus two CSS files (rtl and style.css).
When I logged into cpanel, the child theme folder was in the subdirectory of a different theme. I dragged the folder into the subdirectory of the current theme, and things started not working from then. I also renamed to files to match the parent theme's files exactly, the names which I stated before.
Then I deleted the child theme folder and tried activating a new theme. Now I get a message confirming "New theme activated," but my blog shows up without any CSS styling whatsoever, and the theme not visible.
My website is ceciliatoo.com.
I have no idea how to fix this or what I did wrong. Any help would be appreciated!
