Site crashed after testing parent theme. Please help!

I wanted to test how the site would look like without all the tweaks we have been adding the past weeks and so activated the parent “Intro” theme instead of the child theme (

Bad idea. The site crashed with error message:

Fatal error: Class ‘Intro_Posts’ not found in /customers/3/2/8/ on line 43

How do I revert to the child theme?

Please help, thanks!


Hello LJL,

Connect to your domain over FTP (ex., navigate to wp installation folder (usually hosting root) / wp-content / themes, and delete main Intro theme (download - backup if necessary). After delectation, WP will switch to one of default WP themes, so make sure that you have one installed (upload it over FTP if necessary). At this point your site should work, and default wp theme will be loaded, and you should be able to login to WP admin. Final step is to install main Intro theme again, and after that just activate its child theme.

All the Best!

Still problems:

Fatal error: Cannot redeclare class Intro_Posts in /customers/3/2/8/ on line 125

Please forget my last entry. I managed to get it to work after modifying functions.php.

Thanks for update,

Glad to hear that you have managed to resolve this.

All the Best!
