Your submission could not be processed because a security token was invalid.

This error most often occurs for one of two reasons. Trying to upload a file, or photo which is too large, and it took too long. Otherwise it can occur if you have been on the page a long time, before submitting your post or pressing the upload button.
Please try reloading the page, and attempt your action again. If you were trying to upload an image, please make sure it falls within the site's size constraints.

 

I get this all the time as well, and it never marks the forums read

 

Same here get that same message.

 

I just noticed there is a Mark All Forums Read link at the bottom of the main forum page - when I click that, it works

 

Good find never noticed that will give it a try.

 

Yep works for me too. Must be something screwed up in the link in the top bar only.

 

If you google it, you'll find it's a very common problem on VBulletin sites that use a custom style theme like this one does.
If you scroll all the way down, on the left you'll see a dropdown that says "--FitFreak 3.7". That's the custom style.
Apparently the admins have it locked so you can't select any other style.

The fix seems to be well documented and relatively easy to apply, so either the people with the power to fix it don't read these posts or just don't care that it's broken.

I agree that it's a PITA to have to use the other link on the forum home page.
