Originally assigned to: @IrAlfred on GitHub.

🐛 Bugreport

I sent a plain text message ok and it arrived at the destination. Then I wanted to see if the markdown setting under Site/General would work. After composing the message and clicking send, the screen goes completely blank and nothing is sent and nothing received. I went back to plain text mode and it sent again ok. Tried markdown mode sending couple more times and still wouldn't send and screen went blank. Didn't try html.

Version & Environment

Rev: [not sure, got it around Feb 7 using the install script]

OS: [linux]

I was able to send with markdown without issue. I did find a bug after send causing a 500 error/blank page however I just pushed a fix for that and it was happening after send so probably not what you are seeing.

We use a third party library called parsedown to convert the message body markdown to html on send (clients don't normally natively render markdown), since your site is failing before sending I suspect something want wrong with the "composer install" step of the installation. When you get a blank page it's almost always a server side 500 error and there maybe a clue in your webserver log about what is going wrong. I would try rerunning the composer step and checking the logs if it still fails.

I'm assuming this is what you mean by "composer" and I'm pretty sure I did this before since the errors/warnings look familiar:

I didn't try to update to "composer 2". Do I need it? Anyhow, before and after this it still doesn't work and I get this error in /var/log/apache2/error.log:

Last bit is the problem, you need the DOMDocument PHP class which I think is part of the php-xml package depending on your distro. On debian unstable I have:

jason [ ~/cypht ]$ dpkg -l | grep php | grep xml
ii  php7.4-xml                                  7.4.26-1                              amd64        DOM, SimpleXML, XML, and XSL module for PHP

Yes, installing php7.4-xml on ubuntu 20.04 fixed it. Now it accepts markdown and sends OK.
I guess the INSTALL file needs an addition:

On Debian based systems you can bring in the dependencies this way;
$ sudo apt install php php-fpm php-mbstring php-curl composer php-xml

Thanks!

@kk6mrp the final part of the traceback is cut off so we don't have the actual error here just a trail of crumbs that gets us close :) Some webservers like nginx cap log messages at a max character count, might be the situation here
