Too few arguments to function Responsive_Lightbox_Galleries::admin_post_thumbnai

Hi.

I had custom banners admin part not working because a problem with the interaction with the filter “admin_post_thumbnail_html” since I moved to the latest version of responsive lightbox (2.3.4).

Seems the filter “admin_post_thumbnail_html” expects 3 parameters instead of 2.

I managed to get custom banners admin part working again by changing the line 319 of custom_banners.php from:
echo apply_filters( ‘admin_post_thumbnail_html’, $content, $post->ID );
to:
echo apply_filters( ‘admin_post_thumbnail_html’, $content, $post->ID , null);

The error message is as follows:

Fatal error: Uncaught ArgumentCountError: Too few arguments to function Responsive_Lightbox_Galleries::admin_post_thumbnail_html(),
