Environment Value
Operating system: Linux
PHP: 7.3.10
MySQL: 5.5.5-10.0.38-MariaDB-0ubuntu0.16.04.1
Graphics Library: ImageMagick 6.9.7-4

I use the Carrousel function from the Extended Description plugin on an Additional Pages landing page.

[slider album=10 random=false size=L speed=4 title=false effect=fade arrows=false elastic=false control=false]

After upgrading to piwigo version 13.0.0 the following error appears when loading the page:

Warning:  math: illegal characters in include/smarty/libs/plugins/function.math.php on line 76

And the images are not displayed correctly anymore

Hi
try modify include/smarty/libs/plugins/function.math.php in line 72 for
$operators = '[,+\/*\^%-]'; // Allowed math operators
and it's ok ?
