Error message from joomla

Hello, I correctly created a database on my hosting and installed the template with Hotstart package but it displays an error message in every page of the frontend.
it's the first time I get it, I've already worked with several joomla templates.
Can you help to understand why there is this error message and if there is a way to resolve it?

Strict Standards: Non-static method JApplicationSite::getMenu() should not be called statically, assuming $this from incompatible context in /htdocs/public/www/test/templates/hot_app/index.php on line 240 Strict Standards: Non-static method JApplicationCms::getMenu() should not be called statically, assuming $this from incompatible context in /htdocs/public/www/test/libraries/cms/application/site.php on line 250
Strict Standards: Only variables should be assigned by reference in /htdocs/public/www/test/modules/mod_hot_film_tape/tmpl/default.php on line 13

Thanks in advance

I just resolved, they were just warning messages for developers, I resolved from Global Configuration - Server and set the parameter Error Reporting no None. You can delete this thread... Sorry!
