In my case I faced only one issue related to /home/lkerie/public_html/app/code/Magefan/Blog/Model/ImageUploader.php file
So I did magic like the following:
mv /home/username/public_html/app/code/Magefan/Blog/Model/ImageUploader.php /home/username/public_html/app/code/Magefan/Blog/Model/ImageUploader.php_old
Everything started working as it should
However I then found appropriated for 2.3.5 ImageUploader.php file version
