I'm having problems with online ticket purchase, having previously been able to on Google Chrome. Now, after entering credit card details and clicking pay, the page changes to a blank page. I have done this several times over the last few days. I haven't had any emails confirming purchase and my c/c company can see the attempted purchase but the City website claws back the transaction instead of completing it. I am a Citizens member and buy tickets on a match day basis. This problem was not present earlier in the season. I have been checking the settings on my lap top (Windows 7) and the Mcafee settings but don't see any issues. I have tried Firefox and that wouldn't reveal stadium plan, Flash Player issue, so I updated/downloaded, no difference. I disabled the firewall as well. I rang City but they didn't prove too helpful.
