Blog appears blank after activating the plugin

  • Hello,

    We followed the instructions for install but it seems that the plugin “magically erases” the website after activating. The <body> tag appears empty and the page is blank.

    Any help with this?

    Thanks,
    CR

    This is pretty urgent..

    Hi @cristianroman

    ‘DOMDocument’ class is a core PHP class and the error as you may noticed is that the plugin unable to find it.

    1- make sure your WordPress is up to date & PHP v5 or later.

    2- Make sure the plugin is up to date.

    3- If you have made any changes to Transformer.php in the plugin vendor files; check function transformString & make sure that DomDocument has a backslash exactly before it:
    $document = new \DOMDocument('1.0'); //line 189

    Hi Huthayfa,

    Wordpress and plugin are up to date, PHP version is 7 and I haven’t made any changes to Transformer..
