php warning: fopen(/nas/content/live/lexblogms/wp-content/blogs.dir/1321/files/

Hi! Thank you for the excellent plugin.

After udpating WordPress core and your plugin, we get this php warning:

fopen(/nas/content/live/lexblogms/wp-content/blogs.dir/1321/files/wpcf7_uploads/.htaccess): failed to open stream: Permission denied

Some unique things about our setup:
– It’s a blogs.dir multisite network.
– It’s on WP Engine.
– It’s on php 7.4
– It uses nginx rules instead of htaccess rules
– There are hundreds of blogs on this install, so creating an htaccess file in every folder is not a scalable solution.
