some bugs about rated tactics

[Idochesswork]

Hi Alf,

1. The attribute fallback_tpl="1" messed up:

I used the below shortcode:
[chess tactics="1" tpl="2" db="11" width=480px fallback_tpl="1"]

And even If I logged on or not, the template it used is just unrated.

2. rated tactics call out wrong database to use:
I got some databases:
- Check mate in 1 Whtie - with ID=11
- Check mate in 1 Black - with ID=12

and when I try to call out the database with db="11" or "db"=12, it use wrong database, a kind of several moves tactics that I don't know where they came from
This is the shortcode I used:
[chess tactics="1" tpl="2" db="12" width=480px]

All best to you,

Hi Alf,
I tried to delete cookies and cache, and the db selection works correctly. So I guess it's because of cookies and cache. I really sorry for addressing the wrong issues.

The problems remains are:
1. fallback_tpl attribute seems to be not working.
2. in rated mode, whenever a wrong move is made, the piece stuck on the wrong square. For example, I move the Bishop from c1 to a3. It's a wrong move. And the bishop would stay on a3, instead of returning back to c1. Is would cause some difficulties. May it be automatically dragged back to the c1 square just as unrated tactics mode?

Thank you, Alf.
