Hi,

I'm sorry but I don't know what else could cause this behaviour. It could be caused by some 3rd party plugin interfering with VM Invoice. You can try disabling system plugins in your Joomla's Plugins Manager to see if one of them is causing it.
As we have no other reports if this problem, it seems to be connected to your specific Joomla installation or server configuration. In this case I can only offer you our paid support service to check the problem directly on your website. For pricing please see: www.artio.net/e-shop/support-services/joomla-support-1h

Hello,

yes, it is possible. Just send me your requested user name via e-mail to: Tato emailová adresa je chráněna před spamboty, abyste ji viděli, povolte JavaScript and I will do it.

I know my English's far from perfect, sorry about that.

Now ARTIO Support does not want to care for even one on the three tickets that were supposedly included as we purchased your product?
I see nowhere we need to be NN with an identical issue for ARTIO to give support. Please do your job.

PS: Support asked me to activate error_reporting upon reporting the issue (i.e. no PDF, no error displayed (1st mesage)... Then asked to deactivate it on the server as error_reporting might "cause the issue".

I forgot to say that the component works on a copy of the production website that's running on another server. It's an exact copy with the same plugins and configuration (but the SEO which shouldn't impact here on backend I believe). Respective PHP versions are: 5.4.30 (production) and 5.4.11 (dev).
Really dunno where to look. Apache logs? please say.

Hi,

I'm sorry but our support tickets don't cover specific server configuration or compatibility issues with 3rd party components. According to you the component works correctly on a different server so it is very likely some problem with your server settings and not with our component.
Also if you want to use your support tickets, please follow the steps described in our Support Tutorial on Tickets: www.artio.net/artio-support-system/support-tutorial/tickets

I'm sorry but as I said we haven't encountered the problem you describe before, so I don't know what to advise you.
