There have been a couple of joomla and t4 updates and the issue persists! Again, I have to wonder if I am the one this is happening to. I think not but maybe others don't notice the issue?
Once again, from line 99 error dot php file (under t4bs5blank template) I have removed the 'index.php' from the code you gave me and the redirect to websitename.com/ redirects as it should. But again, this is only temporary until the next update.
<a href="<?php echo $this->baseurl; ?>/"
title="<?php echo Text::('JERROR_LAYOUT_HOME_PAGE'); ?>">
<?php echo Text::('JERROR_LAYOUT_HOME_PAGE'); ?>
</a>
