Redirection issue with some forum topics

[George Notaras]

Sometimes it happens that a topic is not accessible and the browser complains that the page is not redirecting properly. IIRC, I’ve encountered this problem a few times during the last weeks. I think it has to do with some special characters that have been used in the topic title.

I’ve added the modlook tag to such a topic I happened to encounter in my plugin’s support forum. I’m not pasting the link so as to avoid any URL encoding done by the browser when copying the URL.

Trying with curl results in a redirection loop:

Could a moderator or admin please check what might be causing it?

Thanks in advance.

Also, I’d suggest to remove the special characters « and » from the topic title if possible. I hope the user will not mind about it.

That URL works fine for me. No redirects at all. But I’ll adjust the topic slug anyway.

Hi Otto. Thanks for looking into this.

I noticed that the issue happened only when trying to access the topic from a browser in which I was not authenticated (other device). The exact steps were 1) visit the forum’s listing of topics 2) click on the problematic topic 3) result: redirection loop. Also copying the topic link from the forum listing and pasting on a new browser window or terminal also resulted in a redirection loop.

Now it works as expected regardless of how I try to access the topic.

Thanks!

Hi,

Also That URL works fine for me,

For special characters ” in the title of this discussion, the link opens normal for me on Chrome and Firefox (I use an OS X system).

I tried to see the option to change the title of this publication, but I do not see this option, I do not think this is possible.

Thanks!

Thank you George, Thank you Samuel

Hmm, weird. I checked with Firefox, QupZilla and curl and always could reproduce the problem. Anyway, as soon as I notice another topic with this problem, I’ll post more info.

Hey Samuel,

Just wanted to point out that as far as I can tell I haven’t received any email notifications for posts added to the aforementioned topic. But, I have no idea if it’s related to the cause of the redirection issue I had (possibly the special characters of the topic title).

> I haven’t received any email notifications

When a post is flagged as possible spam, the system does not send out emails for it. This is to avoid having email services flag emails from us as spam.

Oh, I see. Thanks for the explanation. Much appreciated.
