Thanks very much jitr
That seems to have done the job! I need to have a look around now and check that with this plugin disabled, we don't have any serious problems with other modules.
A couple of quick questions, ...
1. where can I set tax rate?
2. can I add new fields to reservation form? I need to add passport number.
3. some items (in reservations list) are not translated. Is this easy to correct myself?
4. with a subscription, can I get help with the CSS? (I admit I'm a CSS dummy)
Thanks in advance and a great looking module.
