All links take me to homepage

All the links on my wordpress blog take me to homepage. Even I’m using phpbb and when i go on phpbb which is https://www.rehmanamjad.com/forum/ it takes me to wordpress homepage. I can only access admin panel. I thought it was a plugin so i made them all inactive but it still didn’t work.

Here is my .htaccess code:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress
