Thanks. I tried some things after reading that post, but I still can’t get it to work. My wordpress site with BPS installed is at the root: /public_html/ and the site that is getting the pop-ups blocked is installed at /public_html/example.com/projects and it looks to be blocking the index.php file. I tried adding this to the main site’s htaccess file:
# WP REWRITE LOOP START
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
# Do not apply rules to other child websites &
# do not log errors for these child sites
RewriteRule ^example.com/projects - [L]
Any help would be greatly appreciated. Thanks!
