hello whmcs am not very good at English but i will try my best to explain what i want to do. ----- i need help to create a hook for a custom error page and show it for a specific part of the website instead of the default internal error page. for example lets say a client requested to view the invoice with an invalid invoice id by default whmcs will show him the ops page (the internal error tpl at /templates/example/error/internal-error.tpl) what i want to do is show a different error page for this specific error on the invoice page instead of the default one (/templates/example/error/internal-error.tpl) when an invalid invoice id is provided, i want to show a custom page or a custom tpl without having to edit the default internal-error.tpl itself for example this is what i want to show for customer when they get invalid invoice id error

i have issue with the invoice page in whmcs all the payment methods including paypal show up like this i want to show the full iframe of instead a small part of it like this but i couldent find anything in the css or the invoice tpl to fix it

the old problem was solved but now it doesnt show any products to use it on, and it doesnt want to be deactivated
