Dear experts!
After installing new templates there are w3 validation errors:

Error: A script element with a src attribute must not have a type attribute whose value is anything other than the empty string, a JavaScript MIME type, or module.

The Joomla is the newest version 3.9.8! The template is paid proffesional template (Jp-school) developed by studio.

Is it correct to delete type="... " part?
And where is the location of the files to edit?

Thanks ahead!

Thank you gays for helping.
Do I correctly understanding: these errors do not have any influance for page ranking?

I try to validate by https://html5.validator.nu and ther is the only 1 trouble and 2 warnings. The Error:
Error: The itemprop attribute was specified, but the element is not a property of any item.
From line 214, column 1; to line 214, column 24
</h1>↩<h2 itemprop="headline">

Joomla got the function isHtml5(), so it is setting the attribute only when necessary, but it's not implemented in VM yet.

Yes, <script> is enough for HTML5. Maybe someone got motivated to add the isHtml5 to VM and sends a patch?
