My advice would go against the recommendations above. Do NOT dive in with your own server. Instead get a reseller account with a company that knows what they are doing for your customers and then...

As above, it depends on the payment you are using and if you are using local storage for the cards.

Damn. Looks like it was dug up by a spammer...

If you are not storing the card details (which you would be mad to do anyway) but you are having card details entered on your site then you still need to satisfy a quarterly PCI scan and submit a...

It's not built into the app but you can use Prowl as an addon for notifications:

Not that I'm aware of but that sort of money is hardly going to break the bank...

And once you do purchase a license you can get a free additional developer license for local use.

Can we have an additional poll option for "What a ridiculous suggestion and waste of time" so I can vote please?

There is a closed beta group but apart from that it's a free for all...

Use Winmerge if you're on a Windows machine to compare the new templates against your version and merge the changes in...

Because I wouldn't trust any system, WHMCS or otherwise, to merge my changes into changed template files. vBulletin tried it and every release broke my layout as the changes were merged incorrectly...

Just do what I do for every release and use a compare tool to compare the differences in the templates. I don't know what the Mac equivalent would be but I use http://winmerge.org on Windows.

Any good to you? http://whmcsesxaddon.com/en/index.php

I disagree. It's down to the client to keep accurate accounting records, not you or WHMCS. This is why I export all invoices and payments to Xero which is built for the job...

The client can login...

WHMCS is a billing system first and foremost, not an accounting program.

Which WHMCS version are you running? Were the files located within the WHMCS install?

If you look now you will see that 5.2.2 is released which from what I understand kills the vast majority of issues with 5.2.1. Considering this release came out 48 hours after 5.2.1 that's not a bad...

Seems to me you want everything for nothing. If you are serious about selling VPS servers then you need to invest to do it right. You could in its simplest form get a decent server, slap SolusVM on...

Answers the question...

Do we know exactly when the compromise occurred?

Probably as that's way more important than the ability to take payments after all ;)

You know I did say I would wait but it's plain that they may have forgotten to follow through. Basically they are looking at selecting an ASV at the moment and expect to start PA-DSS evaluation...

Tell the client to use Google apps for business. Not free but at $5/user is hardly a bank breaker either.

Just to update, I have got a response from WHMCS on this issue but they would like to add their own thoughts rather than me posting what the result of the conversation was.

Yep. I put a ticket through asking WHMCS to comment on this thread but so far nada...
