Can you edit your post, putting all that mess in a CODE block!! Do you have EnableViewState set to off globally? .....the man in black fled across the desert..........and the gunslinger followed.....

Well, I tried that also and still i get these errors.
I must say that I get a report about these error messages from my application when it traps them. I havent experienced myself that error when i browsed the website. However, my concern is that some of the users might have got these errors.
Any other advice?
Thanks in advance

If this is a user problem, it may be browser related. Try to get as much info as you can from the user to replicate the problem. .....the man in black fled across the desert..........and the gunslinger followed.....

Here are few "User Agents" strings, where this problem occurs: Code:
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; FunWebProducts)
Mozilla/3.0 (compatible; WebCapture 2.0; Auto; Windows)

Just for my information: Does YAF actually uses the ViewState feature? I have had serveral problems in my web projects, too, so I disabled it completely (except YAF) and I'm very happy with it, because mostly I want to optimize my webs for mobile devices, too, where traffic costs money. Edit: There seems to be a problem with the quotes, too  - Sry for my english BattCursor.Net - Official homepage of that tool for vista laptops!

I've tried that either and it didnt help. BTW, when i tried to post this reply the whole page was messy, with no icons loaded and the textbox size is something like 50*100 pixels !!
(I'm using FF3.0)

now i'm running into this problem, too. lot of viewstate mac and viewstate validation problems  user agents: Code:Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)
Mozilla/0.91 Beta (Windows)
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322; FDM)
Mozilla/4.76 [en] (Windows NT 5.0; U)
Opera/9.0 (Windows NT 5.1; U; en)
Mozilla/4.0 (compatible; Powermarks/3.5; Windows 95/98/2000/NT)
Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.7) Gecko/20011221
Mozilla/5.0 (Windows NT 5.1; U; en) Opera 8.01
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; YPC 3.0.2; .NET CLR 1.1.4322; yplus 4.4.02b) Yet again, viewstate is, sad but true, one of the worst asp.net features ever! It's much better to buy a second or third web server instread using that. It is blowing up html sorce with unsecure viewstate data that even prohibits some browsers accessing the site. also it will exclude search engines that reads only the first x bytes from a web page. Most of them will end up reading useless data because viewstate is placed before page content and has usally much more than 2kb in size. I really want to disable it completely. Never trust what a browser returns, only server data is valid!By the way: of course, I have tried the above steps, except the last one jaben said. to disable encryption and validation... Nothing against you, but this is, as I think, like going online with a clean windows xp install, without patches, servicepacks, firewall and antivirus software while thinking "which hacker should attack my system?" just my 2cents - Sry for my english BattCursor.Net - Official homepage of that tool for vista laptops!

This viewstate problem is causing me a lot of problems. My host informed me that my forum has crashed their server numerous times. They even informed me that they will be forced to terminate my account if not resolve

See other thread, check with web host to see if running as a web farm. If so add MachineKey. Well documented issues with Viewstate and Webfarm configurations. http://forum.yetanotherf...ed-error.aspx#post12984
As previously stated don't use that machine key but google a generator to find your own.  "It's a case of RTFM.. the only problem being we don't have a manual!" When I post FP:Mek in a topic, I'm leaving my footprint there so I can track it once I get into coding/supporting. (Yes I stole this off Ederon  )
