libxml extension not being detected?

[mkap20]

I am running Firefly III version 5.4.6

Description
Fresh install of Firefly III on a FEMP stack. I can successfully reach the login page, but as soon as I click register, it goes to an error that tells me: "Unfortunately, this error was not recoverable :(. Firefly III broke. The error is:" You need to install the libxml extension to use this back end

I've already verified that the libxml extension is installed and enabled. Here's the output from php -m: [PHP Modules] bcmath Core curl date dom fileinfo filter gd hash iconv intl json ldap libxml mbstring mysqli mysqlnd openssl pcre PDO pdo_mysql Phar Reflection session SimpleXML SPL standard tokenizer xml zip zlib

And the appropriate section from php -i confirms this:

libxml

libXML support => active
libXML Compiled Version => 2.9.10
libXML Loaded Version => 20910
libXML streams => enabled

Once I get this error, as soon as I navigate to the Firefly III url, it will show this error page and won't even show the register screen anymore. Only a fresh install of Firefly III will allow me to see the register screen again, after which it will show the error again if I click on the "Register" button.

OS: FreeBSD 12.2 (in a TrueNAS jail)

Is the PHP version you run on the CLI the same as the one your webserver uses? Can you test this in a file like phpinfo.php?

[mkap20]

Yep, I tested it and the page shows 7.4.14, with libxml enabled (everything matching what I saw in the CLI).

[JC5]

Mmmm, sorry, that means I'm already out of ideas. It seems a specific error from the QR code generator for 2FA, but it's not used in the registration flow. Or at least it shouldn't be. I'll do some digging but I'm kind of out of my depth with this one.

[mkap20]

Yeah I'm also stumped right now. I updated FreeBSD and still no luck. I'm pretty sure my FEMP stack is all working correctly, so I'm not sure if it's some bug with Firefly III that I found or not (since I can't really find any other people with this problem). Thanks for your help!

[JC5]

In other code, like a PHPinfo file, can you do something like this?

var_dump(class_exists(\XMLWriter::class));

I'm curious to see what will happen.

https://www.php.net/manual/en/class.xmlwriter.php

[mkap20]

It's returning simply bool(false).

Edit: looks like I got it working! Just needed to install the XMLWriter module (duh). Thanks for your help!
