so it is appearing on all the controllers and actions on your site ? or just SiteController ? – Muhammad Omer Aslam
on all pages in the bottom of the page – Bynd
on all controllers and actions – Bynd
Can you show the url and have you looked into the frontend/web/index.php if there is any echo there?, Did you upgraded the Yii version via composer update – Muhammad Omer Aslam
hmm nothing here that looks odd , try commenting out the <?= $content ?> portion to check if the exception belongs to the content part and narrow it down – Muhammad Omer Aslam

sometimes such error occurs, when after "?>" you put some chars like as space or new line. You need remove them and save file. It may work on localhost, but not working on real hosting.enter image description here

?>
<-- you need remove new line

Following the advice from Murat Kurbanov, I solved my issue on this by closing the php tag at the end of my file. I just put a ?>
