Same error here: An error of type E_ERROR was caused in line 139 of the file /nas/content/live/THEME/wp-content/plugins/stream/classes/class-log.php. Error message: Uncaught ValueError: Unknown format specifier "Q" in /nas/content/live/THEME/wp-content/plugins/stream/classes/class-log.php:139

Getting the same with Stream 4.0.0, also with a Yoast SEO property.

Input

array(3) {
  ["meta_key"]=>
  string(26) "_yoast_wpseo_content_score"
  ["meta_value"]=>
  string(2) "90"
  ["post_type"]=>
  string(4) "page"
}

Error

Fatal error: Uncaught Error: Unknown format specifier ")"
in /app/web/app/plugins/stream/classes/class-log.php on line 131

Call stack:

    vsprintf()
    app/plugins/stream/classes/class-log.php:131

The reason seems to be the unescaped % in the string that gets wrongly parsed by vsprintf.

Wow, somebody reported the exact same issue yesterday: https://wordpress.org/support/topic/fatal-error-when-saving-the-seo-title-meta-with-in-the-post-title/

[krokodok]

This code might be outdated:

https://github.com/xwp/stream/blob/0336294c11ac185629c4fa66b31d18451fe0fa1d/connectors/class-connector-wordpress-seo.php#L418-L435

I found a quick fix / hot patch with str_replace():

sprintf(
    /* translators: %1$s: a meta field title, %2$s: a post title, %3$s: a post type (e.g. "Description", "Hello World", "Post") */
    __( 'Updated "%1$s" of "%2$s" %3$s', 'stream' ),
    $field['title'],
    str_replace('%', '%%', $post->post_title),
    $post_type_label
),

I found, that a lot of the other connectors are passing database strings to log() as well, without checking if they contain %. This should be patched for all these occurrences, right?

Is this fixed by https://github.com/xwp/stream/pull/1508 ?

[tharsheblows]
