Error: Smarty internal templatebase.php(157)

[Euronymous]

Hello,

prestashop 1.7.2.4 - I got it an error: Smarty internal templatebase.php(157):

The provider says it might be about an incompatible module with Prestashop 1.7. But i didnot install any module more that 3 months.

Can you tell me please, what i cause this error.

The error is that the site stops working for 30s and then everything is fine.

Thank you, for your help, Petr.
