Bought and tested Artio Booking v. 1.2.16 for joomla 1.5.25 on my test server (linux - PHP Version 5.2.17). I got everything working fine back-end and front-end. Then I set Book it up again (from scratch) on my site which is on a windows server.
[Windows NT WEB10 5.2 build 3790 (Windows Server 2003 Standard Edition Service Pack 2) i586 ] PHP Version 5.3.3
Everything seemed to work fine until I tried the "Make a Reservation" button (booking detail page) on the front end. The page came up, missing all css instruction, just basic text I had put in for the object at the back-end appeared in the top left hand corner, not using the correct character set and there was no sign of the calendar. (See attachment)
I have had some exchange with my hosting provider. Two times we have set the Joomla up again and then installed Book it - with no success, always the same outcome.
I couldn't find a detailed server requirements on your site to forward to my hosting provider. Do you have such a document or do you have any ideas about what could be wrong?
Thanks
