Support » Theme: Customizr » Fatal Error After Update

  • Hi, I backedup my site, updated to WP 3.8 then updated Customizr. I am using a child theme which is activated. After updating to WP 3.8, the site was still good. After updating the theme, I received this message:

    Fatal error: Cannot redeclare class TC_slider in /homepages/11/d364271349/htdocs/synergy/wp-content/themes/customizr/parts/class-content-slider.php on line 15

    Please help.

  • Reinstalled backup. Site is still down with fatal error.

    What happens if you activate Customizr, rather than the child theme?

    If that gets the site back up, tell us what’s in your child theme.

    It’s looking like the theme is not compatible with WP 3.8…

    The Child Theme you mean?

    Not sure. Right now that’s unlikely that the issue is with the Child Theme as there are minimal changes from the original and it’s mainly basic CSS. Still working on restoring…

    Customizr 3.1.5 is fine with WP 3.8 — loads of us are using it with no problems. It has to be the child theme or your installation.

    The error is telling you that you are trying to load the same function twice. So either you have something in your child theme that is doing this, or you have an extra copy of one of the theme files in the theme folders.

    The first step is to see if Customizr works on its own. If it doesn’t then there is something corrupted in your installation of Customizr. Delete it from the WordPress dashboard and reinstall it from the dashboard.

    Once you have Customizr (with no child) working then we can try to figure out what’s wrong with the child.

    Awesome @electricfeet, thanks! I’ve got the site restored to a previous version. Am going to dig in and work on your suggestions tomorrow…… Thanks everyone!

    @electricfeet, Well I had a full version of functions.php in the Child Theme directory. I removed that. Do you think that would fix it?

    Yes, quite likely – copying a functions file to a child theme generally causes major problems. You may want to review:
