    Hello,

    I just checked my error_log file and found this warning over and over again.. I was hoping someone could explain it and possibility present a fix.

    Thank you!

    PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘improved_trim_excerpt’ not found or invalid function name in /home/thecircl/public_html/wp-includes/plugin.php on line 214

    function apply_filters( $tag, $value ) {
    global $wp_filter, $merged_filters, $wp_current_filter;

    $args = array();

    // Do ‘all’ actions first.
    if ( isset($wp_filter[‘all’]) ) {
    $wp_current_filter[] = $tag;
    $args = func_get_args();
    _wp_call_all_hook($args);
    }

    if ( !isset($wp_filter[$tag]) ) {
    if ( isset($wp_filter[‘all’]) )
    array_pop($wp_current_filter);
    return $value;
    }

    if ( !isset($wp_filter[‘all’]) )
    $wp_current_filter[] = $tag;

    // Sort.
    if ( !isset( $merged_filters[ $tag ] ) ) {
    ksort($wp_filter[$tag]);
    $merged_filters[ $tag ] = true;
    }

    reset( $wp_filter[ $tag ] );

    if ( empty($args) )
    $args = func_get_args();

    do {
    foreach( (array) current($wp_filter[$tag]) as $the_ )
    if ( !is_null($the_[‘function’]) ){
    $args[1] = $value;
    **LINE 214** $value = call_user_func_array($the_[‘function’], array_slice($args, 1, (int) $the_[‘accepted_args’]));
    }
    } while ( next($wp_filter[$tag]) !== false );
    array_pop( $wp_current_filter );
    return $value;
    }

    – What theme are you using, and..

    – Can you stop or change the error message by temporarily changing themes

    I am using the theme movite.

    https://www.magpress.com/wordpress-themes/movite.html

    I am not sure If i can stop/change the error message when switching themes. Since the site is active so i have not tried.

    As far as I know, improved_trim_excerpt() isn’t a native WordPress function.

    There seems to be a few references (link goes to Google) to using it in a filter for customizing/replacing the wp_trim_excerpt function. That makes me think it may be something related to your theme, or maybe a plugin meant to customize excerpts. The theme is a commercial purchase, so there’s no way to take a look at the functions file from here.

    improved_trim_excerpt() is in the formatting.php of wp-includes/formatting.php

    I found one article relating to this issue. https://aaronrussell.co.uk/legacy/improving-wordpress-the_excerpt/

    Also the theme is free if you select “download” under the image in the article or use this link https://www.magpress.com/download/movite.zip

    If it is, I’m not seeing it. I think you might be confusing it with wp_trim_excerpt

    https://core.trac.www.ads-software.com/browser/branches/4.0/src/wp-includes/formatting.php

    I don’t find it in the Code Reference either.

    ..and a quick grep of that theme directory didn’t turn up the function.

    Are you using any plugins that customize your excerpts, or has anyone customized your theme’s functions using that filter?

    I have been looking around in my plugin’s, but i do not see anything that is causing an issue. I will be testing a couple things in the next couple days and let you know.
