Hello there

i have just overwrited the old National Flag Extension files with new ones and my whole forum does not work

- how can i deactivate the extension through FTP?
- where can i download the old plugin?

thanks a lot, btw the web is http://www.overland.sk/forum and I have the latest 3.1 forum

Edit:
found the old version and rewrited the files through FTP. its working, but i have the old version.

Not sure how you updated but I just did it on a test forum and it seemed to work just fine.
