If you get this error on theme installation

“Are you sure you want to do this?”

This message shows because your upload limit is less than theme size.

Check all server requirements are met, and especially the max upload size – https://help.wpresidence.net/article/theme-wordpress-server-requirements/

You need to change this PHP value (server value) upload_max_filesize in PHP.ini to at least 64MB from hosting settings (please ask hosting support for assistance if you don’t know how to edit this yourself.

How to check max upload size:

Go to tools – import

Run importer

Check this is 64M or more

If you have 64M and more you can install the theme via wp-admin easily.
