I have clear cache by CLI "php Flarum cache:clear" and force delete file in cache & formatter but is not working.

JoshyPHP

Post your Renderer_f1aee4dfa982f4663e2f4b2880649f402b888b25.php file somewhere and I'll look into it. However, there's like a 70% chance that you're hitting a weird bug that occurs in some combinations of some versions of PHP + libxml2 that I've never been able to reproduce. In that case, you can try upgrading/downgrading/reinstalling a different version of PHP and/or libxml2.

Hi @JoshyPHP ,

I debugged and found the issue at this point where the node was returned as null, leading to an error.

I added a condition + the cache and reloaded the website, and then it worked fine. After it ran normally, the condition I added was no longer needed.

JoshyPHP

Do you still have the file? I'd like to take a look at it.

There should never be a null argument passed to at(). There are two ways that it can happen:

I've seen some prebuilt binaries of PHP + libxml2 incorrectly return null for DOMNode properties that could not be null in practice, such as the $documentElement property of a node attached to a valid DOMDocument. I've never been able to narrow down the source of that bug and compiling the same versions from source produced the correct results. I have never seen this issue on PHP 8.3.
There is a logic error in my code. In that case I'd definitely want to know about it in order to fix it.

Unrelated to this, I think that your PHP installation doesn't have ext/tokenizer enabled. If it had, the screenshot you posted would show $html .= '<pre><code>'; rather than the multiple concatenations.

I have phpinfo, tokenizer & libxml2 is enable is server and tried clearing cache again at Flarum Dashboard and the issue happened again.

I looked at your Renderer_*.php file and I can't make sense of it. The code is wrong, it's been generated incorrectly and in a way that I'm not able to reproduce. That could indicate an error at the PHP level. It could be related to ext/tokenizer, but it's theoretically possible that a bug in the way constants are inlined by ext/opcache would cause the PHP generator to behave in an unpredictable way. You can try disabling OPCache and restarting your PHP server to see if that helps.

If you want to diagnose the issue, you could try running the library's test suite on your server. The PHP CLI executable won't necessarily be the same as the one used by your server, though. Here's how to clone the repository and run the test suite:

$ git clone --depth=1 https://github.com/s9e/TextFormatter.git
$ cd TextFormatter
$ composer install --dev
$ ./vendor/bin/phpunit

As a workaround, you could also create an extension that configures the s9e\TextFormatter\Renderer instance to set $renderer->enableQuickRenderer = false;. That will disable the half of the code that's flagrantly wrong. Then you'll have to hope the other half is in working condition. 😐

Thank you so much, I have tried but it's not working.

Strangely when i rebuild the app at RunCloud the forum works normally again. It might be because of PHP as you said, i will try to setup on another server to find the root cause.
