Option 1Wordfence
This behavior is often related to the Wordfence plugin in either the current site or a site above the site being installing to. For example if installingto /public_html/mysite and WordFence is installed on another WordPress site at /public_html then the location of either plugin can cause issues.

To Resolve:

• While you install, temporarily disable WordFence. Additionally you may also need to temporarily comment out the line that beginswith ‘auto_prepend_file’ in .htaccess and .user.ini files in the parent site’s directory.
• Alternatively go to your web sites control cPanel > file manage > public_html > show hidden files. Edit the user.ini file and make sure the path showsthe correct path, if it shows the path from the original account path. Once that is changed the site should work.
