Can't reply to thread, redirected to create a new topic.

Edit: Generalized the problem... Messages (PMs, topics, replies) won't go through if

[url=http://Link ]Text[/url] is used 4+ times. Used to work, no recent changes to the forum or any mods.


I created a thread that I've updated frequently with links in this format, but for some reason it doesn't let me reply anymore. When I click preview or submit, it redirects me to create a new topic.

This is what I'm trying to reply with... In fact when I try replying with this post in other threads, the same thing happens.

This is the thread in question: http://www.forumvancouver.com/threads/groupon-steal-the-deal-wagjag-and-other-group-buy-websites-updated-daily.31/

New info: when I tried pming the message in using the code bbc tags, it won't send.

Instead it returns this:

The following error or errors occurred while posting this message:

    * Your session timed out while posting. Please try to re-submit your message.
    * No recipients specified.
    * No subject was filled in.
    * The message body was left empty.

I am puzzled because this hasn't been an issue before. I tried turning off SimpleSEF for awhile but the problem still exists.

So far, it looks like I can't post anything (reply, thread, pm) if my message contains what I have in the first post.

[Kill Em All]

Are you getting any errors in your forum error logs?

I have a feeling that one of your mods is causing the problem. Even if you did try turning them off, the code is still there.

Maybe this could even be a theme problem, do you get this problem on the default theme?

[yoghurtfarmer]

Thanks for that suggestion, I just tried out the default theme and the problem's still there.

It's weird because this problem only started recently...I thought maybe there's some kind of spam feature that's blocking it since I've posted those same links so many times?

So far, I can post other things just fine.

No errors out of the ordinary. I do get some errors from SimpleSEF but I've always gotten those since I installed the mod.

[yoghurtfarmer]

I've checked a bunch of my mods and the problem's still there...but I did manage to generalize what triggers the problem.

Users get redirected whenever there are 4 or more url tags...but only if they are in the following form (with the url in the square bracket):

Code Select Expand


[url=http://URL]Text[/url]


So... I can have three of these and it will post, but as soon as I have four of them, the post won't go through and I'll get redirected... or in the case of a pm, it will give me an error.

I've made no modifications to the site and haven't installed any new mods, so I don't know what's up.

[Kill Em All]

Does that occur in other topics too that you post 4 or more url tags? I can post 4 urls on my test site just fine in the same posts. Try creating a new topic on your site and posting 4 or more urls. There should be no spam filter preventing you from doing that AFAIK.

[yoghurtfarmer]

It happens site wide.. new topics, replies and private messages can't be sent if they contain 4 or more of those URL tags.

This is just a problem that started recently without any changes to the site. I've been posting those tags for a month without issue.

[Kill Em All]

Ask your host if they made any recent changes to any configurations, or in a new directory install a fresh version of SMF 2.0 RC3 and see if the problem still occurs. If not, add each mod one by one and try it in between mods. This is either a mod problem or a server configuration problem. I'm gonna bet something went haywire with a mod though.

[yoghurtfarmer]

Okay will do that.

I used Notepad++ to compare the forum files now and a few days ago and found this in post.php:

Current (Line 1524):

Code Select Expand


if ($smcFunc['htmltrim'](strip_tags(parse_bbc($_POST['message'], false), '<img><object><embed>')) === '' && (!allowedTo('admin_forum') || strpos($_POST['message'], '[html]') === false))


Before (Line 1524):

Code Select Expand


if ($smcFunc['htmltrim'](strip_tags(parse_bbc($_POST['message'], false), '<img><object><embed><iframe>')) === '' && (!allowedTo('admin_forum') || strpos($_POST['message'], '[html]') === false))


There was also a similar thing on Line 2741 where an iframe was missing in the current version. The rest of the file is the same... Could that be the cause of it?

[Kill Em All]

Thats strange, did that just disappear?

By default, there shouldn't be one there anyways unless a mod added it there....

[yoghurtfarmer]

Figured out it was Aeva that added it, but it's not related to the problem.

I did a clean install of SMF 2.0 RC3 with no mods, default theme. Same problem, except this time I don't even get redirected to a "Create Topic page", I just get a Forbidden error message.

"Forbidden

You don't have permission to access /test forum/index.php on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
Apache Server at averagepalate.co.cc Port 80"

[yoghurtfarmer]

I guess this is server related then, but do you know what would cause it?

This DOESN'T cause any issues

This DOESN'T either

This DOES cause the problem

Code Select Expand


[url=http://]Text[/url]
[url=http://]Text[/url]
[url=http://]Text[/url]
[url=http://]Text[/url]


So to me, it's the url=http:// (when there are at least 4 of them) part that causes the following error message:

Forbidden

You don't have permission to access /testforum/index.php on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

[Kill Em All]

Hum, this is just a hunch. Make sure your index.php is CHMOD to 644.

[yoghurtfarmer]

^ Yup they are.

[Kill Em All]

Considering this is happening through everything such as posts and pms, and that it started happening without anything being changed on your forum specifically, I'm gonna say your host messed around with something.
