#1078 – Error when upgrading to Joomla 4

Status: Closed - Category: Showtime Image Gallery
 Hello Lefteris,

On my clients testsite I get an error when I upgrade the site to Joomla 4:

Deprecated: htmlspecialchars(): Passing null to parameter #1 ($string) of type string is deprecated in /home/mol4test/domains/pecars.123testdomein.nl/public_html/mm4/modules/mod_showtime/mod_showtime.php on line 11

What can this be?

I think I managed to get rid of the error myself through a commit on Github.
I seems to work but maybe you can confirm this?

In short this is what I needed to change.

$moduleAttribs['class'] = 'moduletable ' . htmlspecialchars($params->get('moduleclass_sfx'), ENT_QUOTES, 'UTF-8');

change to:

$moduleAttribs['class'] = 'moduletable ' . htmlspecialchars($params->get('moduleclass_sfx', ''), ENT_QUOTES, 'UTF-8');
