Version 2.1.3 is now published. Hopefully that fixes the problem for you, if not, let me know.

I’m setting this topic as “resolved”, but I can’t set it as “unresolved” if you experience any problems.

Thanks for the extra context. It was impossible for me to fix this, as I couldn’t find a problem until your comment here.

Could you try this version of the plugin to see if it fixes your problem?

It has no affect on my test setup. I can upload videos to the header just fine on it, and they don’t interfere with how the plugin works, so I’m not able to debug this myself sorry. If we’re lucky, it will do the trick. If it works, I’ll release it as the official version.

I misunderstood originally. You are trying to add videos via the customizer, not this plugin, but you are getting errors because of this plugin. That is a definite bug if it is the case. I’m working on it right now. I’ll try to fix out as soon as possible.

Thanks for alerting me to this problem. It didn’t show up during the testing process.

Sorry about this!

@siliconforks  pointed this out on GitHub. The problem was caused by a clash between the PSR container loader I added to Disable Emoji’s and some plugins/themes using very very old incompatible container setups.

It’s now patched and shouldn’t happen again.

GD is a PHP library which needs to be installed on the server itself. Most standard web hosting services offer it by default. This can be a little difficult if you don’t have some server management experience.

Here are some instructions to turn it on that I found online …

Installing GD Library for PHP

Here are the instructions for installing the GD library for PHP on different systems:

Linux (Ubuntu/Debian)

For PHP 7.x/8.x:
sudo apt update
sudo apt install php-gd

For specific PHP versions: For PHP 8.1

sudo apt install php8.1-gd For PHP 8.0

sudo apt install php8.0-gd For PHP 7.4

sudo apt install php7.4-gd

Linux (CentOS/RHEL/Rocky Linux)

Using yum/dnf: CentOS 7/RHEL 7

sudo yum install php-gd CentOS 8+/RHEL 8+/Rocky Linux

sudo dnf install php-gd

macOS

Using Homebrew: If you have PHP installed via Homebrew

brew install php GD is typically included by default Or reinstall with GD explicitly

brew reinstall php –with-gd

Using MacPorts:
sudo port install php81-gd

Windows

Using XAMPP/WAMP:

1. GD extension is usually pre-installed and enabled
2. Check your php.ini file and ensure this line is uncommented:
   extension=gd

Manual installation:

1. Download the appropriate PHP GD extension DLL
2. Place it in your PHP extensions directory
3. Add extension=gd to your php.ini file

Compiling from Source (Advanced)

If you need to compile PHP with GD support: Install GD development libraries first

sudo apt install libgd-dev libpng-dev libjpeg-dev libfreetype6-dev Configure PHP with GD support

./configure –with-gd –with-jpeg –with-png –with-freetype Compile and install

make && sudo make install

Verification

After installation, restart your web server and verify GD is working:

Restart Web Server

Don’t forget to restart your web server after installation: Apache

sudo systemctl restart apache2 or

sudo service apache2 restart Nginx with PHP-FPM

sudo systemctl restart nginx
sudo systemctl restart php-fpm or

sudo service nginx restart
sudo service php-fpm restart

Common Issues

Permission issues: Make sure your web server user has proper permissions to load the extension.

Wrong PHP version: Ensure you’re installing the GD extension for the correct PHP version your web server is using.

Missing dependencies: On some systems, you might need additional image libraries like libjpeg, libpng, or libfreetype.

The exact installation method depends on your operating system and how PHP was installed on your system. The package manager approach (apt, yum, brew) is usually the simplest and most reliable method.

This update was wrong. I’m fixing it now.
