Hmm, the error comes from this file:
cca line: 165:
if (!fwrite($this->file, $line . "\n"))
throw new RuntimeException('Cannot write to log file.');
Seems like Joomla! cannot write entry to log file (it uses fwrite, so there can be problems with permissions or ownership - no FTP layer can be used), but why it is in checkout, really no idea :idea:
1) what you do you mean with "paid"
2) for now there is no russian language as I know, there are two payment methods: cash on delivery, PayPal. Payment methods are stored as plugins, so more can be written, Phoca Cart is still in development version, so there are only two for now. And one more info. Phoca Cart is not VirtueMart, it should be simple and easy extension, it does not make sense to do another VirtueMart. The extension should be simple and easy so it can be maintained well.
3) It is written like other Phoca extensions - in Joomla! MVC pattern - outputs can be overridden, there are layouts for HTML parts.@SDKiller
Yes, sometimes I update only releases, not the code. Now I have updated it. https://github.com/PhocaCz/PhocaCart
