Active Topics Filter broken?

Hey all, 1st of all, let me apologise if this question has been answered elsewhere in this forum. I have searched but can find queries similar to mine, but no end fix..so here goes...

Up until yesterday forum (access 7.51a) worked fine. Now I find that the active topics wont show any posts unless the filter is set to "yesterday" when it will show all post made within the last 24 hours. All other filters "last login, last 15 mins right up to 16 hours" all show no posts.

I have edited my common.asp, admin/common.asp and active_topics.asp to show LCID 2057(UK-English) and have checked that server(based in England) is also set to this.

Here is a link to my forum, you dont have to register, to see what the problem is. If you click on active topics and select "yesterday" you will see a good many posts all made within the last few hours, but if you select anything other than "yesterday", you see no posts.

Can anyone help, or have any ideas?

Thanks mate, I have set up a 7.8 forum on my site and transferred database across. Unfortunately it is still the same, no filters on active topics work except "yesterday". (I have also edited new common, and active_topics file to LCID 2057 for UK).

Any more info you can help me with, please?

Any ideas, Anyone?

My sanity is beginning to suffer and I am pulling my hair (what's left of it) out!
