Cannot Unsticky Thread
 

i cant unsticky thread
show this error

i have read all trhead about it
but i still confused :confused: pls help me

It sounds like when you did your last vbulletin upgrade, you didn't upgrade your style templates. Go to - vboptions > General Settings > Add Template Name in HTML Comments > set to Yes and then go back to the page where you clicked unstick and look at the page source. Find the <form> that was supposed to perform the action. Get the name of the template that contains the form. Go to edit that form and View History > Compare and you should see a line about a securitytoken highlighted. Add that line to your template.

all my template is up to date
but still cant unsticky thread

You must not of reverted one and just hit save on your version to dismiss it

If you are positive all your templates have been properly upgraded (that means either reverting it or doing a Compare between your version and the default Jelsoft one for every single template in red and for every single non-Jelsoft template(modifications)), then try disabling your plugins and then see if you still get the error.
Note: To temporarily disable the plugin system, edit config.php and add this line right under <?php
