Is there a way i can remove the personal website box during registration and in the profile cause i dont want people posting their own sites. I dont allow outside links on my site
If you mean Custom Profile Field
then just disable it in ACP > Configurations > Profile Field.
This doesn't cover the website box that the OP wants to remove.
@OP: To stop people entering websites into the box, do the following.
Open AdminCP -> Templates / Styles -> Templates -> *expand template set* -> User Control Panel Templates -> usercp_profile.
Find the following:
<tr>
<td colspan="3"><span class="smalltext">{$lang->website_url}</span></td>
</tr>
<tr>
<td colspan="3"><input type="text" class="textbox" name="website" size="25" maxlength="75" value="{$user['website']}" /></td>
</tr>
Remove it. I've tested this myself and that should be the only location you need to remove
