Hello, restore application back from your backup. Repository version does not contain fix what I have done for you.

Hello,
I don't think it's possible to only restore the Artio booking with akeeba backup which is the backup I have.
If I want to restore averything then we will loose two weeks of orders in Virtue Mart webbshop so that is no good option.
Is there no other way to fix it?

Guys I am also on IIS8 and PHP 5.4. Please post the fix here because after an update from 1.4x to 1.56 my booking lists also crashes the system, it also seems related to the calendars.

So now we have a pattern where IIS8 is the issue I think. But still you fixed it last time so please fix it now as well and let me knwo how to proceed when an update is needed.
And there is no option to make a backup as doing a backup of the whole site would make things very complicated with orders in teh webshop disappearing etc. At least this time it's a problem so a fix would be good. You can do it maybe when you do the custom work?

Ok got an error in sight:

500 - DateTime::__construct(): Failed to parse time string (2013-W00) at position 4 (-): Unexpected character

Version 1.56

Please Artio support team, can you help us with this?
Last time I got fast assistance but this time it was 6 days ago I got any response to this.
Please.
