Security Token Issue
 

For some reason I have some users, not all, telling me they are getting error messages every time they try to post - regarding a missing security token.

We have nearly 200,000 registered users, but only a minor amount are having these problems.

How can I correct this problem?

First thing to do is collate all the complaints you have and check each name against the usergroups and write down which group they belong to, I suspect they are all in one group and a mod or plugin you have is coded wrong.

The fact that you have 200,000 members is great but you'll find that 90% of them have only posted maybe once and 90% of the remaining 10% have only posted a few times which is why it doesn't become an issue to many times

You should be able to use a "log parser" and search for the errors. Then use @Simon_ Lloyd technique above. Happy hunting. :)

If you have a large active board a log parser is indispensable in my opinion.

If you have different styles, try posting using each style. It could also be that users using a certain style are getting the error.

Could this be a browser error? I'm logging in as some of these users and unable to replicate the error.

Could be, but did you read Kevin's post about about the style? Have you tried posting using each of your styles?

Could you have Cookies and HTTP Header Options > Session Timeout set too low and they're just timing out?

It still happens here and there.

Today it actually happened to me, for the first time, and I post every day, several times a day. But it only happened once so far.

Would posting the following in the postbit template correct the issue.

"<input type="hidden" name="securitytoken" value="$bbuserinfo[securitytoken]" />"

Very likely.

Ahh I didn't realize you had this up here, see my pm I just sent ;).
