Custom Template not enabled when creating new invoice

Hi,

I’ve created simple invoices and quote templates by simply hiding some info of the default ones. The templates are selectable in the settings.
The files have 777 permissions just in case.
However when I create a new invoice, I always see the default template when generating a pdf.

My second perhaps silly question, if I resolve the first one:
what is the best way of testing my custom template?
I guess any change will be visible when I click downlaod pdf in a newly created invoice. Is that right?

Thanks in advance!

EDIT: Nevermind, it was a server’s issue. Thanks
