In summary, this problem is caused by Prism plugin code highlighting and a possible crash of that prevented the reply box JS from running.

I am speaking about this thread: https://www.physicsforums.com/threads/recursion-with-a-runnable-in-java.1047991/

This is what I am seeing:

Tried from Chrome and Firefox. Same issue. But in other threads, the reply box is working fine.

Does anyone else face the same issue? Mods?

Me too (Firefox on Android).

Workaround: click Reply in a post and the edit box appears with the quoted material. You can then edit.

Interesting. Once I have replied, I can see the edit box. If I refresh the page, it's gone again.

Brave, I get a couple of JS errors and no reply box.

Prism plugin is code highlighting? Maybe a crash of that prevented the reply box JS from running.

Minimized code to trigger the problem:
[CODE highlight=""13, 25""]foo[/CODE]
I can reproduce the problem by posting this piece of code in other threads. If I replace the double "" by single " it works, so that's the key problem. I fixed it in the linked thread.

Same issue, same poster in this post. Looks like something about how @Darkmisc is posting code is causing those doubled double quotes.

It's coming from the interactive editor:

> Optional. Line numbers you want to highlight. For example, "2, 4-6" will highlight lines 2, 4, 5 and 6.

It wants the user to write e.g. 2,4-6, so it adds quotation marks around the user input. If the user plugs in "2, 4-6" with quotation marks then the post ends up with double quotation marks, which then breaks the execution of the highlighting script. That means the best fix will have two elements:
- check if the user input has quotes already, and remove them before processing the string further to create valid syntax
- catch the invalid input when showing the comment so it doesn't break things

In the meantime: @Darkmisc please don't add " " around the lines you want to highlight.

There is small update to the core software. I'll find a time in the next week to run it.
