it's worth noting that there is a hotfix available for a PayPal issue in v7.10.1- it might be worth checking whether this will fix your issue too.

Vale la pena señalar que hay un hotfix disponible para un problema de PayPal en v7.10.1. Puede valer la pena verificar si esto también solucionará su problema.

not that i'm aware of - if it's an issue that WHMCS believe they have fixed in a v7.10 release, I would think it unlikely they would release a hotfix for v7.9... they would probably expect, and prefer, you to upgrade to v7.10.2

although sometimes hotfixes exist internally within WHMCS and don't get released publicly - so I think only someone from WHMCS could give you a definitive answer on this.

Hola jesus

no es que yo sepa: si es un problema que WHMCS cree que han solucionado en una versión v7.10, creo que es poco probable que lancen una revisión para v7.9 ... probablemente esperarían y preferirían, usted para actualizar a v7.10.2

aunque a veces existen revisiones internas dentro de WHMCS y no se publican, por lo que creo que solo alguien de WHMCS podría darle una respuesta definitiva al respecto.

thanks for answering.

I have updated to the latest version 7.10.2

and change the template to six (default)

however the problem persists.

the buttons are not yet displayed.

any new thoughts?

Hi all,

If you're experiencing this error in v7.10.2, please refer to this documentation to troubleshoot the cause: https://docs.whmcs.com/PayPal_Checkout#An_unknown_error_occurred._Please_try_again

@JesusSuarz This hotfix does not apply to v7.9. Please apply the 7.10.2 update.

 

 

Hello

After exhausting all my options I started looking at all my installed modules.

the following module presented the problem: https://marketplace.whmcs.com/product/2966-services-fee

I had to remove it.
