Hello,
It's because you have added the index.php to the urls :( The index_page in config should be blank. If you change index_page the url structure will change and would result in failure of ajax calls.
Please reset it back to default and try to change the lines below in the .htaccess
```
# For godady Shared Hosting Server uncomment the line below
RewriteRule ^(.*)$ index.php?/$1 [L] // I HAVE UNCOMMENTED THIS
# Please comment this if you have uncommented the above
# RewriteRule ^(.*)$ index.php/$1 [NC,L,QSA] // I HAVE COMMENTED THIS
```
If you have upload the files in subdirectory `d` then you can uncomment the `# RewriteBase /forums/` and change it to `RewriteBase /d/` in the .htaccess file.
I hope it will resolve the issue. If you can't make it work, please let me know your server details in private reply. I will try to check for you.

Thank you
