Symptoms
-
Clicking the Domains> example.com > PHP Settings > View the phpinfo() page button results in the following error:
Error: Unable to retrieve information about the PHP configuration.
-
"FPM application served by Apache" or another Apache-based handler is selected at the Domains > example.com > PHP Settings page
Cause
Restrictive Apache rewrite rules are blocking access to the domain's phpinfo() page. For example:
#<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_URI} "!(^|/).well-known/([^./]+./?)+$" [NC]
RewriteCond %{SCRIPT_FILENAME} -d [OR]
RewriteCond %{SCRIPT_FILENAME} -f
RewriteRule "(^|/)." - [F]
</IfModule>
<IfModule mod_authz_core.c>
<FilesMatch "(^#.*#|.(bak|conf|dist|fla|in[ci]|log|orig|psd|sh|sql|sw[op])|~)$">
Require all denied
</FilesMatch>
</IfModule>
Resolution
Disable restrictive rewrite rules
If directives are set in Plesk
2. Navigate to Domains > example.com > Apache & nginx Settings > Additional Apache Directives section
3. Remove restrictive rules from Additional Apache directives for HTTP/HTTPS fields
if directives are set in the .htaccess file
1. Connect to the server via SSH
2. Open the domain's .htaccess file via any text editor (for example, vim):
# vi /var/www/vhosts/example.com/httpdocs/.htaccess
3. Remove restrictive rules
