Glossary index shortcode issue

iThoughts Tooltip Glossary is my choice for implementing a Glossary and subglossaries in my site. It is really easy to use, pretty customizable, and works quite well. I only miss the ability to associate categories and tags to each term of the glossary.

Now I got that the “Add a Glossary Index” button from the TinyMCE Editor just puts a blank character ” ” in page.

I then tried to manually insert the two shortcodes “[Glossary A-to-Z]” and “[Glossary List]” shown in the screenshorts provided, but to no avail.

Then, from the code of the plugin, I figured out that the right shortcodes are “[glossary_atoz]” and “[glossary_term_list]”. So I tried these ones instead and the two types of glossary indexes were rightly displayed in the frontend.

But I got also the following warnings:

Warning: count(): Parameter must be an array or an object that implements Countable in /…/wp-content/plugins/ithoughts-tooltip-glossary/class/shortcode/class-glossarylist.php on line 153

… on line 189

… on line 104

(I suppose that the duplicity of warnings is due to the presence of the two shortcodes).

So I resorted to the next page from the author: https://www.gerkindevelopment.net/en/tips/shortcodes-post-excerpts/ were I read that: “Sometimes, depending on your theme and configuration, your shortcodes contents are stripped out with the shortcode itself.”

Following the directions there given, I inserted the following code in my child-theme’s functions.php file:

// SOLVING AN ISSUE WITH THE REPLACE SHORTCODES OF ITHOUGHTS TOOLTIP GLOSSARY
function keep_shortcodes_content($content = ""){
????$replacedShortcodes = array(
    '/[(glossary_atoz|glossary_term_list|glossary-(?:mediatip|tooltip|glossary))(?:.*?)(?:/]|](.*?)[/1])/' => "$2"
);
	$original = $content;
????if ( '' == $content ) {
????????$content = get_the_content('');
????????foreach($replacedShortcodes as $regex => $replace){
????????????$content = preg_replace($regex, $replace, $content);
????????}
????????$content = strip_shortcodes( $content );
????????$content = apply_filters('the_content', $content);
????????$excerpt_length = apply_filters('excerpt_length', 55);
????????$excerpt_more = apply_filters('excerpt_more', ' ' . '[...]');
????????$content = wp_trim_words( $content, $excerpt_length, $excerpt_more );
????}
????return apply_filters('wp_trim_excerpt', $content, $original);
}
remove_filter( 'get_the_excerpt', 'wp_trim_excerpt'??);
add_filter( 'get_the_excerpt', "keep_shortcodes_content" );

The result was then the following error message:

Parse error: syntax error, unexpected ‘$replacedShortcodes’ (T_VARIABLE) in /…/wp-content/themes/responsivepro-child/functions.php on line 45

I would appreciate any help to fix this issue. Thank you very much.
