In WordPress you can get the error “RSS Error: XML or PCRE extensions not loaded!”
To fix this run the following commands in command line:
sudo apt install php-xmlsudo service apache2 restartWhen you reload your WordPress page the error should now be gone.
If you’re running a fresh install of WordPress chances are that you will see the error
“The optional module, imagick, is not installed, or has been disabled.”
To solve this error go to command line and type:
sudo apt install php-imagickWhen the install is done you need to restart Apache:
sudo service apache2 restartIf you go to your WordPress site and refresh the error should now be gone.
Often if you install WordPress on Debian Apache you will get the error
“The optional module, curl, is not installed, or has been disabled.”
To install curl go to your command line and type:
sudo apt install curl php-curlWhen it’s done installing you need to restart apache:
sudo service apache2 restartcurl is now installed and if you go to your WordPress installation now the error should be gone.
Follow these simple steps if you wan’t to set up Pi-hole on an existing Apache web server or if you wan’t to install Apache later on.
If you have allready installed Pi-hole with the included lighttpd web server this will not work.
Run the Pi-hole install:
curl -sSL https://install.pi-hole.net | bashWhen asked “Do you wish to install the web server” select “No”.
Finish the Pi-hole installation process and run:
sudo usermod -a -G pihole www-dataThen install sqlite3:
sudo apt install php-sqlite3Restart Apache:
sudo service apache2 restartIf you don’t allready have PHP installed you will also need to run:
sudo apt install php libapache2-mod-phpAnd restart Apache again:
sudo service apache2 restartIf you have successfully set up Pi-hole with Apache the address http://ip-address/admin should now work.
