  • Hi,
    The plugin is giving this error:

    What’s causing this, and how can we fix it?
    Thanks

  • Since the author hasn’t replied or address this, here’s the fix…

    Basically in PHP 7.3 it’s using a more strict engine to process regular expressions. In this case, the hyphens need escaped on line 379 (escape means add a backslash before the hyphen, there are 2 in this line)

    Change This:

    if ( ! preg_match_all('/( [\\w_-]+ |([\\w-_]+)\s*=\\s*("[^"]*"|\'[^\']*\'|[^"\'\\s>]*))/', $tag, $matches, PREG_SET_ORDER) )

    To This:

    if ( ! preg_match_all('/( [\\w_\-]+ |([\\w\-_]+)\s*=\\s*("[^"]*"|\'[^\']*\'|[^"\'\\s>]*))/', $tag, $matches, PREG_SET_ORDER) )

    Many thanks to forwardtrends – it was easy to fix! Harald
