Atimes, while trying to upload a wordpress theme, I get this error message
The uploaded file exceeds the upload_max_filesize directive in php.ini
Well, when this happens, instead of disturbing myself on how to increase the limit, which might still not work, I will just sign in to the site cPanel and upload the zip file to the themes directory and unzip it there. Thereafter, I will sign in to my wordpress dashboard and activate the theme.
If you don’t know how to navigate to the wordpress themes directory in cPanel, here is how :
file manager > public_html > wp-content > themes
If you want to login to your site cPanel, go to 
yoursite.com/cpanel
