Prevent Direct Access (PDA) Gold
- There are some Raw URLs limitations on Nginx servers.
- Unable to auto-activate subsite license with renewed licenses.
- Protected files on subsites will be removed if deactivating plugin (WIP).
- Fail to remove pda testing files after checking rewrite rules in some environment.
- _pda folder is looped in some setup.
- Protected files return to 404 page if their names contain more than 1 dot, e.g. “sample.pdf.pdf”.
- Media “Bulk Actions” might cause errors when users select no files (WordPress issue).
- Total clicks of private download link (MP3, MP4) may be more than the actual clicks if the browsers play them automatically.
- Due to Cross-Origin Read Blocking (CORB), you can’t access the protected files embedded in a different site even when you have the right permission.
Incompatible plugins
- Better Search & Replace (BSR) plugin: Their known issue makes all PDA Gold settings return to default values after BSR runs.
- JWT Auth – WordPress JSON Web Token Authentication plugin: Prevent our configuration popup from displaying.
- If you get the “Failed to load PDF documentation” error when accessing protected links or private links in some cases, it might be a conflict with one of the following features:
- Minification and Gzip Compression features of Breeze plugin
- Minify the HTML Output feature of SG Optimizer plugin
- Pages excluded from search results using Search Exclude plugin won’t appear under our Search & Replace (S&R) search box. Simply “re-include” these pages by unticking the checkboxes on the plugin’s settings accordingly to show them on our S&R feature.
Resolved issues
- Conflict with Use directory for default language option of WPML plugin: This option will make protected links not to work properly
You can resolved the issue by adding the following code snippet to your (child) theme’s functions.php file.
Requirement: Prevent Direct Access Gold version 3.3.0 or greater
add_filter( 'pda_get_home_url', 'pda_change_wppml_home_url', 10, 1 ); function pda_change_wppml_home_url( $home_url ) { if ( ! class_exists( 'SitePress' ) ) { return $home_url; } global $sitepress; $language_negotiation_type = $sitepress->get_setting( 'language_negotiation_type' ); if ( '1' !== $language_negotiation_type ) { return $home_url; } $setting_urls = $sitepress->get_setting( 'urls' ); if ( empty( $setting_urls['directory_for_default_language'] ) ) { return $home_url; } return trailingslashit( get_option( 'home' ) ); }

Plain Permalink
Our plugin works well with Pretty Permalinks but not Plain Permalinks on Apache as WordPress won’t generate any htaccess rules. To resolve this, you can select one of these options:
(1) Enable Keep Raw URLs option under our settings page
(2) Put our .htaccess rules as below:
<IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] # Prevent Direct Access Rewrite Rules RewriteRule ^private/([a-zA-Z0-9-_.]+)$ index.php?pda_v3_pf=$1&pdav3_rexypo=ymerexy [L] RewriteCond %{HTTP_USER_AGENT} !facebookexternalhit/[0-9] RewriteCond %{HTTP_USER_AGENT} !Twitterbot/[0-9] RewriteCond %{HTTP_USER_AGENT} !Googlebot/[0-9] RewriteRule ^wp-content/uploads(/_pda/.*\.\w+)$ index.php?pda_v3_pf=$1 [QSA,L] # Prevent Direct Access Rewrite Rules End </IfModule> # BEGIN WordPress # END WordPress

Watermark WordPress Files
Resolved issues:

Conflict with PDA Protect Videos extension: Can’t configure S3 bucket(resolved in 1.1.5.3)- AWS config warning:
AWS SDK tries to load configuration from ~/.aws/config, but accessing your home directory is prohibited in PHP configuration.
There are 2 solutions to resolve this:
- Configure open_basedir in php.ini that allows ~/.aws/config
- Set ENV variable to the default AWS configuration file.
To do so, you can put this code at the end of your (child) theme functions.php:
# Change www.yourwebsite.com to your actual website URL putenv('AWS_CONFIG_FILE=/web/htdocs/www.yourwebsite.com/home/');
