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.
To install TeamSpeak Server on a Raspberry Pi you need to install an emulator. In other words you have to make your ARM processor understand packages made for x86 processors.
In this guide I will use the Box86 emulator.
1: First we have to update the system with these two commands:
sudo apt updatesudo apt upgrade2: Now we need to install all the necessary packages to compile Box86:
sudo apt install git build-essential cmake3: Now clone the latest GitHub version:
git clone https://github.com/ptitSeb/box86If you have a 64-bit operating system follow these steps. If your operating system is 32-bit; don’t!
(4): Add the 32-bit architecture to the package manager:
sudo dpkg --add-architecture armhf(5): Update the package manager:
sudo apt update(6): Install the needed packages:
sudo apt install gcc-arm-linux-gnueabihf libc6:armhf libncurses5:armhf libstdc++6:armhf1: Change into the driectory where we downloaded Box86 to:
cd ~/box862: Make a new directory called ‘Build’ and change into it:
mkdir buildcd build3: Now choose the right command for your Raspberry Pi and OS:
For Raspberry Pi 4, 32-bit:
cmake .. -DRPI4=1 -DCMAKE_BUILD_TYPE=RelWithDebInfoFor Raspberry Pi 4, 64-bit:
cmake .. -DRPI4ARM64=1 -DCMAKE_BUILD_TYPE=RelWithDebInfoFor Raspberry Pi 3:
cmake .. -DRPI3=1 -DCMAKE_BUILD_TYPE=RelWithDebInfoFor Raspberry Pi 2:
cmake .. -DRPI2=1 -DCMAKE_BUILD_TYPE=RelWithDebInfo4: Now we have to compile Box86. This can take a very long time!
make -j$(nproc)5: Once finished we have to install the compiled Box86 emulator:
sudo make install6: Now we have to restart the systemd-binfmt service:
sudo systemctl restart systemd-binfmt7: All we have to do now is reboot:
sudo reboot1: Start by updating:
sudo apt updatesudo apt upgrade2: Install ‘jq’:
sudo apt install jq3: Create user ‘teamspeak’:
sudo adduser teamspeakJust hit Enter and skip through and confirm with Y(es).
4: Switch user to ‘teamspeak’:
sudo su - teamspeak5: Download the latest Linux x86 version of TeamSpeak Server:
wget $(curl -Ls 'https://www.teamspeak.com/versions/server.json' | jq -r '.linux.x86.mirrors | values[]')6: Extract the downloaded package:
tar xvf teamspeak3-server_linux_x86-*7: Remove the package from where we extracted:
rm teamspeak3-server_linux_x86-*8: Change into the TeamSpeak Server directory:
cd teamspeak3-server_linux_x869: If you agree to the TeamSpeak license agreement:
touch .ts3server_license_accepted10: Start the server for the first time:
./ts3server11: On the first startup it will post an admin token (privilege key) that you will need later in the TeamSpeak Client.
Copy it and save it!
12: When you have copied the token you can shutdown the server for now by pressing Ctrl+C
13: Exit the ‘teamspeak’ user:
exit1: Create a service file:
sudo nano /etc/systemd/system/teamspeak3.service2: Copy-paste the following into the service file:
[Unit]
Description=TeamSpeak 3 Server
After=network.target
[Service]
WorkingDirectory=/home/teamspeak/teamspeak3-server_linux_x86/
User=teamspeak
ExecStart=/home/teamspeak/teamspeak3-server_linux_x86/ts3server
Restart=always
RestartSec=15
Restart=on-failure
[Install]
WantedBy=multi-user.target3: Save and exit the file by pressing Ctrl+X, then Y and then Enter.
4: Reload systemctl daemon:
sudo systemctl daemon-reload5: Enable the TeamSpeak Server service:
sudo systemctl enable teamspeak36: Start the TeamSpeak Server:
sudo systemctl start teamspeak37: Check the status of the TeamSpeak Server:
sudo systemctl status teamspeak3
8: Exit by pressing Ctrl+C
Congratulations! If you have followed every step of this tutorial you should now have a working TeamSpeak3 Server running on your Raspberry Pi.

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.
