    would greatly appreciate some help:

    Ok so getting white screen of death, ran debugger and got following syntax error:

    Parse error: syntax error, unexpected ‘bfa_ata4’ (T_STRING), expecting ‘,’ or ‘;’ in D:\home\site\wwwroot\wp-content\themes\atahualpa\functions.php on line 273

    Line 273 is as follows:

    if (delete_option(‘bfa_ata4’)) echo ‘<span style=”color:green;font-weight:bold;”>Successfully deleted option ‘bfa_ata4′ …</span>’;

    whole function is:

    function bfa_delete_bfa_ata4() {
    check_ajax_referer( “delete_bfa_ata4” );
    if (delete_option(‘bfa_ata4’)) echo ‘<span style=”color:green;font-weight:bold;”>Successfully deleted option ‘bfa_ata4′ …</span>’;
    else echo ‘<span style=”color:green;font-weight:bold;”>Something went wrong…</span>’;
    die();
    }

    Have deactivated all plugins but does not make a difference

    thanks!

    You’re using the single-quotes inside a string using single quoted. Thats the problem. Any single quotes inside the string should be escaped, as \'

    thanks very much for your advice, I have no changed to:

    if (delete_option(‘bfa_ata4’)) echo ‘<span style=”color:green;font-weight:bold;”>Successfully deleted option “bfa_ata4” …</span>’;

    However the letter ‘s’ is now not displaying correctly (you can see here)

    is this correct?

    function bfa_delete_bfa_ata4() {
    check_ajax_referer( “delete_bfa_ata4” );
    if (delete_option(‘bfa_ata4’)) echo ‘<span style=”color:green;font-weight:bold;”>Successfully deleted option \’bfa_ata4\’ …</span>’;
    else echo ‘<span style=”color:green;font-weight:bold;”>Something went wrong…</span>’;
    die();
    }

    Now have is as \’, however getting the same syntax error

    Then change the single quotes for double quotes.

    It’s one thing that I should have remembered. PHP treats strings between double-quotes and single-quotes differently. If you use double-quotes, the text is evaluated and parsed, but using single quotes, it’s taken “as is”.

    function bfa_delete_bfa_ata4() {
    check_ajax_referer( "delete_bfa_ata4" );
    if (delete_option('bfa_ata4')) {
        echo '<span style="color:green;font-weight:bold;">Successfully deleted option "bfa_ata4" ...</span>';
    }
    else {
        echo '<span style="color:green;font-weight:bold;">Something went wrong...</span>';
    }
    die();
}
