Unable to reply to some discussions

Th0mC

Hi,
I'm unable to reply to some discussions on my forum.
I don't understand what is the common point between all discussions that can't be replied.
The only thing I saw is that on these discussions, the counter on the right of the discussion is not working:

And when I try to reply, It's just looking "grey" but there is no reply window:

I specify that this is the same behaviour on chrome or safari and It tried to activate the Debug mode but I don't have any log.

Thanks in advance for your help.

Th0mC it looks like a javascript error. Can you open the browser console and try again ? A javascript error message will likely appear in the console. Chrome usually has the most detaikled error messages for this kind of stuff.

Thanks. That's right.
Here is the error I get opening a discussion in which I can't reply and the same appears when I try to reply.

Argh I'm really stuck here.
I really need help. I can do everything needed but I don't have any idea of what 🙁
Please help 😉

Th0mC do you know if it happens to others users, in particular those without any group ? Or only admins ?

The easiest for you would be to disable each extension until you find a culprit. But it's impractical on a production forum... Unless it's not active yet ?

Is there maybe a way you give me access to an account on the forum and tell me where I can try posting so I can take a look ? You can contact me via Discord to send credentials (Clark#1615, you can find me via the Flarum server. and you can switch to French when contacting me outside of this forum 😉 )

EDIT: the only extensions from your list that I suspect could interfere and produce such an error would be the Fancybox and maybe the Poll extension. Can you try disabling each of them in turn and try again ?

Th0mC

You rocks! This is a FancyBox extension issue 🙂.
How I can help to resolve this?

Note: I tried with another "simple" user before to disable FancyBox extension and same issue.

clarkwinkelmann

Th0mC good progress 👌

Now that's tricky. There's probably a combination of extensions causing this, or a particular formatting that breaks fancybox. I just tested fancybox alone and couldn't find any issue.

Was the issue happening on any discussion ? Was it happening in discussions with no images at all ?

Th0mC

clarkwinkelmann
No, only on a few ones.
Yes, on discussions with no image at all.

Th0mC and clarkwinkelmann I can confirm that this issue is related to the FancyBox extension 🙂 (where index.js:59 Uncaught TypeError: this.isEditing is not a function is pointing towards the JS code in the FancyBox extension, more specifically this line)
as shown below:
