    Dear Support, 

    I have updated my wordpress and since than, when I try to update page I get this message:

    Hi,

    tried steps in that article.

    Ive even tried to reinstall WordPress to version 5.0.3. and reinstall Salient template but nothing has helped. 

    Still getting that warning.

    I am using PHP 7.3 and I think that it all is happening because of this warning: 

    Warning: preg_match_all(): Compilation failed: invalid range in character class at offset 11 in /data/web/virtuals/217263/virtual/www/domains/hubalovsky.eu/wp-content/plugins/js_composer_salient/include/autoload/hook-vc-grid.php on line 163

    Hey there,

    Thanks for reaching in,

    Please try downgrading to PHP version 7.1 or 7.2.

    Regards

    Hello,

    I tried PHP 7.2. and it seems, that the bug problem is away. Anyway there is still one problem - I can't change Navigation Header colors. 

    I am trying to downgrade to PHP 7.1. to check, if it helps…


    Anyway it is bit of a shame, that we can't use PHP 7.3... 7.3. is much faster! Hope you will update salient so we can happily use PHP 7.3.
