Hello.

A fresh install of https://www.joomshaper.com/joomla-templates/kidzy from the Quickstart Pack Joomla 4 does not work. I did the installation 4 times, on different servers. I have set all the necessary technical requirements.

http://domowe.h2g.pl/fr/ Class "JString" not found http://domowe.h2g.pl/en/component/404/?Itemid=488 Component not found. Why doesn't the menu work on mobile devices? When you click next to the language switcher in "Login/Signup", the fields are inactive.

There are also other errors like:

Deprecated : Creation of dynamic property cpanelClass::$cmsUserVars is deprecated in /home/przedszkole/domains/domowe.h2g.pl/public_html/administrator/components/com_acymailing/helpers/helper.php on line 1383

Deprecated : Creation of dynamic property cpanelClass::$values is deprecated in /home/przedszkole/domains/domowe.h2g.pl/public_html/administrator/components/com_acymailing/classes/cpanel.php on line 17

Deprecated : Creation of dynamic property plgSystemRegacymailing::$components is deprecated in /home/przedszkole/domains/domowe.h2g.pl/public_html/plugins/system/regacymailing/regacymailing.php on line 154

Please help.
