Turning on glossary plugin makes that articles content not to be shown at all

I recently revised this plugin. Please make sure you have latest 8.18 version.

Hello,

I installed this plugin (together with Cobalt latest version 8.773-Stable), but I get the following errors:

before the article body:

Warning: preg_replace(): Unknown modifier 'N' in /plugins/content/glossary/glossary.php on line 94
Warning: preg_replace(): Unknown modifier 'c' in /plugins/content/glossary/glossary.php on line 94
Warning: preg_replace(): Unknown modifier 'd' in /plugins/content/glossary/glossary.php on line 94
Warning: preg_replace(): Unknown modifier 'r' in /plugins/content/glossary/glossary.php on line 94

and after the article body:

Warning: preg_replace(): Unknown modifier 'N' in /plugins/content/glossary/glossary.php on line 94
Warning: preg_replace(): Unknown modifier 'c' in /plugins/content/glossary/glossary.php on line 94
Warning: preg_replace(): Unknown modifier 'd' in /plugins/content/glossary/glossary.php on line 94
Warning: preg_replace(): Unknown modifier 'r' in /plugins/content/glossary/glossary.php on line 94

I use Joomla! 3.9.12 on PHP 7.2.9.

Hello again,

I noticed there are some mistakes in the code.

The first occurrence of

htmlspecialchars($vall->field_value, ENT_COMPAT, 'UTF-8'),

should be replaced for $vall->title, otherwise the contents appears as title too.

I tested the component and plugin on two websites. On one of them it worked better, but it still added the tooltipr code within the HTML tags. The regex that works for me is "~\b(" . preg_quote($vall->title) . ")\b(?![^<]*>)~", the whole line being:

$article->text = preg_replace("~\b(" . preg_quote($vall->title) . ")\b(?![^<]*>)~", $string, $article->text);

Regards, George

(I'd like to ask some admin to delete the first message, as the code is messed up and I have no way to delete it myself. Thanks.)

That is almost exactly what I have in latest Glossary plugin.
