.html files of a website show a blank page page when Apache PageSpeed module is enabled on a Plesk server

For best experience, Apache PageSpeed recommends to have static files processed by Apache. To enable this setting, follow the steps:

Disabling smart static files processing via Plesk

1. Go to Domains > example.com > Apache & nginx Settings and disable the option Smart static files processing.

2. Click OK to apply the changes.

   Note: It is not possible to manage this option via service plan settings.

To disable smart static files processing by nginx for all newly created domains, apply the following steps:

1. Connect to the server via SSH.

2. Create the sh script with any text editor, for example:

   # vi /usr/local/psa/bin/script.sh

3. Add the following lines in the script:

   CONFIG_TEXT: #!/bin/bash
   echo "starting" >> /tmp/event_handler.log
   plesk bin subscription --update-web-server-settings ${NEW_DOMAIN_NAME} -nginx-transparent-mode true
   echo "added ${NEW_DOMAIN_NAME}" >> /tmp/event_handler.log

4. Make it executable:

   # chmod 755 /usr/local/psa/bin/script.sh

5. Go to Tools & Settings > Event Manager > Add Event Handler

6. Choose "Physical hosting created" as an event and put the following command in the "Command" field:

   # sh /usr/local/psa/bin/script.sh

7. Click OK. From now on, all newly created domains will have this option disabled.

Disabling smart static files processing via a command-line interface

Connect to the server via SSH and disable Smart static files processing using the following command:

• For a domain:

  # plesk bin subscription --update-web-server-settings example.net -nginx-transparent-mode true

• For all domains:

  # for subs in `plesk bin site --list`; do echo Processing subscription... $subs; plesk bin subscription --update-web-server-settings $subs -nginx-transparent-mode true; done

If Smart static files processing must remain enabled, turn off Apache PageSpeed module so that it does not interfere with static files processing:

Turning off Apache PageSpeed module via Plesk

1. Go to Tools & Settings > Apache Web Server.

2. Uncheck pagespeed (and pagespeed_ap24 if enabled) and click OK.

Turning off Apache PageSpeed module via a command-line interface

1. Connect to the Plesk server via SSH.

2. Disable Apache mod_pagespeed:

   • on CentOS/RHEL-based distributions

     # mv /etc/httpd/conf.d/pagespeed.conf /etc/httpd/conf.d/pagespeed.conf.bak

   • on Debian/Ubuntu-based distributions

     # a2dismod pagespeed

3. Restart Apache web-server:
   

   • on CentOS/RHEL-based distributions

     # service httpd restart

   • on Debian/Ubuntu-based distributions

     # service apache2 restart

4. Verify that the module has been disabled - there must be no output in the command below:

   • on CentOS/RHEL-based distributions

     # httpd -M | grep pagespeed

   • on Debian/Ubuntu-based distributions

     # apache2ctl -M | grep pagespeed
