I worked it out. To do so, may vary from each theme. Find the php file/s that contain: echo $OUTPUT->login_info();
In my case, there were two. (theme fusion): frontpage.php and general.php, both in the layout folder of the theme.
Comment out the line above, and you've done it. Note: There is more than one copy of the line in each file (header and footer).
Once you've done it, you'll notice that the alignment is out by one line.
To fix it, find the start of the PHP tag before the commented out line: eg.) <?php if (
Before it, copy and paste the following into the lines ABOVE the tag.
It should then look something like this (this is the header, the footer looks different):
<?php if (!
echo $OUTPUT->lang_menu(); }
If done right, the login link and text should be removed, and everything stayed in allignment!
If anyone needs any help, just ask
