I am getting a very weird error. Orders are not being shown for approval, random invoices are appearing and when I click on them they have no ID. A customer complained about that in a ticket which I can not open because it says the ID does not exist. Can not open last ticket -> it redirects to id 0 Check pending orders -> it says 303 records found showing 50 out of 300 but it shows empty still Check invoices on the user of the ticket, it is a randomly generated invoice that I can not open -> it has ID 0 yet it has a charge of 18 USD Nothing of that works, the installation is fully bugged for some reason. No errors in activity log. Error started after I migrated the WHMCS installation to a new server. Then I migrated just the database back as there were so many errors regarding php configurations and versions, etc... Errors appeared as soon as the installation was migrated for the first time and have still been there.
