MyBB Community Forums

I made a forum www.just4masti.co.cc n it was opening the sub forum n forums. Then I tried adding some cool looks to it but cancelled all later.
Then I changed the types of attachments n user groups setting.

Now none of the sub forum opens.
www.just4masti.co.cc/forum-3.html

dude,don't worry,don't just hastle,its cool,I also got scared when I was new,can you just make sure that in your root(main directory) where your forums are installed has htaccess file? I guess you haven't changed it yet,download it again and open htaccess.txt and save it as only "htaccess" with option ALL FILES and not .txt and then upload that file and it should be all fine then

got it myself my mistake next time I wont forget to change the directory name while changing forum name.
