activate PRO with purchase code?

Hi, sorry for the trouble but I’m not sure I understand your problem. To install the PRO version you have to remove the lite version and upload the PRO one, there shouldn’t be problems with that, I have some sites with GoDaddy and never had problems.

The confirmation Email is sent by Envato so try contact them.

It turns out the issue is one of expectations. I am new to WordPress and am only now understanding it’s mechanisms, in this case the whole plugin/code upload process. I’d expected to get a serial number and upgrade that way, i.e. put it in and unlock, the way most applications work these days. I see that WordPress really hasn’t outgrown it’s roots in early HTML. It is really old an clunky in basic organization… but perhaps some advantages to that too as you’re expected to get under the hood a bit more.

We prefer not to use that kind of activation as it implies publish the entire source code.

where is the purchase code

I was trying to submit a query for support.
The interface no longer appears for changing the images in a gallery. Any ideas what could cause this? i.e. the rainbow-coloured interface simply dissapeared
