Error on SermonCast module

Hello, thank you for the SermonSpeaker extension.

There is error on SermonCast module:
Deprecated: htmlspecialchars(): Passing null to parameter #1 ($string) of type string is deprecated in .../modules/mod_sermoncast/mod_sermoncast.php on line 17

Is it an important error? Displayed with max error reporting.

PHP 8.1, Joomla ‎4.4.14, SermonCast 6.0.0
 

Thanks for the notice. I will have to take care of that indeed.

"Deprecated" means that it is still working, but it will break in the future PHP version 9.0.
That message should only show in the max setting (meant for developers). For a productive site, you should set error reporting to a lesser setting like "none" anyway. So it shouldn't affect your site in any way.
