Thanks a lot Rick. I've tried to follow the way with the mPDF. Unfortunately, composer was not installed. I've tried to install it as described via the setup.sh script, but now ended up in my whole tiki wiki not showing any pages a lot of times. Only sometime, loading works. Not sure what I broke
Attached is the cli output for my attempt to install it. Any ideas what the issue could be?
from the cli output it looks to me that the last command
bash ./setup.sh -p php7.3-cli composer worked (somehow). Didn't it? Anyway, I would try:
sh ./setup.sh -p php7.1-cli composer
