[Forum] Uploading attachments has stopped functioning

[eboggs_jkvl]

I've very recently started to get this error message when uploading files from my PC to my forum as attachments.

"406 IOErrorEvent type=IOerror bubbles=false cancelable=false eventphase=2 text="error#2038"

I'm running vBulletin 4.2.0

It was working and now it's stopped. I select the file. It starts to upload and then I get the red "!".


TIA

More information. I tried it on my laptop running W8, same error

I went to my iPad, tried it on there and it uploaded just fine.

I am using W8 on the desktop that ALSO fails to upload.


Using the same browser (Firefox) and Windows 8, I just put a file from my PC to the forum as an attachment. The forum is running vBulletin 3.8.5

What has change in the LAST UPDATE to VB 4 that is causing this issue with W8?

My son, who lives 150 miles away has W7. He has access to the forum with vBulletin 4.2.0 He just added an attachment to the same forum that I CAN'T add the attachment but he is using Window 7


W8 can't add attachments to vBulletine 4.2.0


I need help here!

What happens when you don't use the flash uploader but the standard one?

What happens when you don't use the flash uploader but the standard one?

I disabled all of my Add-Ons in firefox and it still failed.

The issue turned out to be a Mod_sec issue between windows 8 and vBulletin 4.X


Here's what was done to correct the issue.

This is the error log message from the mod_sec file:


.[Sat Dec 15 11:35:44 2012] [error] [client XXX.XXX.XXX.XXX] ModSecurity:
Access denied with code 406 (phase 2). Pattern match "^Shockwave Flash" at REQUEST_HEADERS:User-Agent. [file "/path/to/mod_sec/file/modsec2.user.conf"]


Inserted this into mod_sec2 whitelist file


[line "204"] [id "########"] [hostname "www.yoursite.com"] [uri "/PATH/TO/mod_sec FILE"] [unique_id "XXXXXXXXXXXXXXXXXXX"] <LocationMatch "$URI$"> SecRuleRemoveById $ID</LocationMatch>




Most of that is Greek to me and I hope it makes sense to the more talented users on here.
