some wrong with my Payment Modules

Dear all,

Please help me to check what happen with Payment Modules?

Warning: include(/home/shiqing1/public_html/liannaka/includes/languages/english/modules/payment/postforskott.php) [function.include]: failed to open stream: No such file or directory in /home/shiqing1/public_html/liannaka/admin/modules.php on line 173

Warning: include() [function.include]: Failed opening '/home/shiqing1/public_html/liannaka/includes/languages/english/modules/payment/postforskott.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/shiqing1/public_html/liannaka/admin/modules.php on line 173

It's telling you that you have a file missing. Have you checked whether the file is there?

I have checked it,but i can't find the file.

So it sounds as though you have a payment module installed, but are missing one or both of the files that it needs to operate.

If you're not intending to use this payment module, then you'll need to uninstall it. If you do plan to use it, you will need to get the files again and re-install them in the appropriate locations.

How to remove this module?Thanks!

Admin > Modules > Payments,
and remove the appropriate files from /includes/modules/payment and /includes/languages/english/modules/payment

That bit of insight above has solved one of my issues.
After ugrading 1.3.7 to 1.3.8a somehow the modules page in admin was really all over the place.
Files in my custom folder were missing, so moved them about and deleted the other ones Im never likely to use, and it seems ok, but for actual module testing.

One file out of place is enough to muck up, probelm is which and where! Feedback on forum I agree is much better than results by PM.
