your wordpress already sent some data to the browser, and when any data is sent, the headers are sent as well.

I would suggest you to use buffers (ob_start, ob_end_flush, ...) but it's on a general purpose, I do not know if it is appliable in your case, i'm not really working with wordpress structure.

I think this is just the difference between git repos and prepared packages, that is cloning a git repo vs a dist(zip/tar) file. Once cached the zip file just needs to be unzipped and you are done.

For a git repo, cloning is an operation that requires a bit more time, it is likely is going over the network to ensure the cached repo is still up to date, then doing the actual cached repo to working directory clone.

If you want your own packages to load from cache try distributing them in dist (zip/tar) format.

The first exception thrown means "Hey, there is a exception that you haven't yet handled using try ... catch", you can ignore that unless you want to do something with it, but seeing that you are here, the only thing you'd want to do with it is solve it.
The second exception means that the class is not know to PHP, meaning that it is not included/required anywhere before calling the class. Which in your case probably means that a autoloader does not work as expected or the file is in the wrong place for the autoloader.

Make sure you are doing the following:

• including the autoloader file as early as possible
• including the autoloader of composer(if using composer)
• have the autoloaders registered (read how to here)
• have the DomPDF class in a location that gets autoloaded
