    Hello,

    I installed the plugin and clicking “activate the plugin” will cause an error and WP reacts no more ans the screen gets just white. I can only work again by deleting the plugin/file per ftp.

    What can I do?

    Thanks for your help

    Hey Ben

    Are you on a development environment? Do you have some login details (and ftp access to disable the plugin if I need to)?

    Thanks

    Is this a development environment or a live site?

    Thanks

    Hello Ross,

    you think I’ll get the plugin to work? I tried it again but always comes the error when I will activate it 🙁

    Hey Ben

    I’m not sure the issue is exactly but it seems like something in your environment.

    I enabled WP_DEBUG on your site to see if there were any errors, and I got a lot of errors coming through.

    You can find them in your wp-content folder in the file debug.log.

    Now, when you enable S&F – the error message that you receive is

    Fatal error: Call to a member function get_queried_object() on null in /mnt/webw/d0/98/56857798/htdocs/WordPress_07/wp-includes/query.php on line 42

    I’ve now disabled the WP_DEBUG again however you need to enable this and fix your errors.

    I can see some errors in there that are to do with out of date plugins / functions being used – so I think its likely that one of your plugins, or possibly your theme is causing some of your issues.

    So, to isolate the issue, I would first, disable all plugins, and then try to enable S&F
    If it still causes issues, I would try a different theme, and then try to re enable S&F

    And if that still doesn’t work, then I would try to fix all the errors in your site – as these may be the culprit.

    Just to let you know, you don’t have to delete S&F from the plugins folder, you can just rename the folder to get your site up and running again – it should be quicker to debug by doing this.

    Thanks
