Tasks to start with:

- creating a test version (preferably on your own local server or hosted)

- updating Wordpress to the current version (6.3)

- update Woocommerce to the current version (8.)

- update of the theme (Shoptimizer)

- configuration of some caching plugin (I use hosting on LH.pl Mango package with SSH and Redis)

- configuration of the Paynow payment gateway (mBank plugin - currently it throws a fatal error after activation)

Monthly tasks:
