Hello, sorry for what is probably a ridiculous question.
Our wordpress site was migrated to a new server by our host, the domain is unchanged. Now several of the CIVICRM features are not working anymore. Such as payment processing for example or signing up to our newsletter. One of the issues for example is our stripe webhook failing as it now can't reach https://example.org.au/?page=CiviCRM&q=civicrm/payment/ipn/3. When I try to go to the live links for contribution pages, it just shows: "Do not delete this page. Page content is generated by CiviCRM."
I've cleared the cache and reset the paths and looked at the civicrm.settings.php files but couldn't find a place where I had to link to a new IP address. I've also looked for a guide on the CiviCRM page but was unable to find clear instructions on what to do.
If someone can point me in the right direction it would be super appreciated, thank you for the help
