Support » Plugin: Swift Performance Lite » Fatal Error – duplicate wordpress

  • Resolved Jejoi

    Hi there,

    I have my current wordpress site at “xxx.com” then, I want to duplicate the current wordpress site inside the current directory “xxx.com/dev” for development purpose.

    The duplication process was working fine but I’ve got below error.

    Fatal error: Cannot declare class Swift_Performance, because the name is already in use in /public_html/dev/wp-content/plugins/swift-performance/performance.php on line 12

    Then I try to remove the swift-performance folder from the “xxx.com/dev/” plugin folder and everything works as it should be.

    I noticed that swift plugins cause this kind of errors. How can I solve this?

    note:
    public_html – current live wordpress directory
    public_html/dev – development wordpress directory

  • Most likely you need to uninstall Swift from dev installation and have a clean / new Swift installation.

    Thanks for understanding!

    This error is caused by the swift must-use plugin. It’s enough to delete the swift must-use plugin from the folder wp-content/mu-plugins.

    In the recent version of the Swift plugin, this error should be fixed already.
