    On our site since a few days comes the following error:

    Warning: Parameter 1 to W3_Plugin_TotalCache::ob_callback() expected to be a reference, value given in /html/wp-includes/functions.php on line 3549

    can you help please?

  • I had the exact same issue, here is what you need to do

    go to the path “wp-content\plugins\w3-total-cache\lib\W3\Plugin\TotalCache.php”

    Open the file TotalCache.php, and look for the function called function ob_callback. The code will look like

    function ob_callback(&$buffer) {

    Remove the “&”, so your code now will look like –

    function ob_callback($buffer) {
