 * Hi everyone.
 * We want to keep our site secure we do that by updating the PHP. We want to update
   our sites to 8.1 but it gives an error message on this plugin. Our programmer
   indicates the following: **It is important that the Deprecated messages below
   be resolved first by plugin and theme developers.**
 * **Deprecated**: Using ${expr} (variable variables) in strings is deprecated, 
   use {${expr}} instead in **/home/magneig77/domains/magnetarvismagneet.nl/public_html/
   wp-content/plugins/mollie-payments-for-woocommerce/src/Log/WcPsrLoggerAdapter.
