Security Token?
 

So installed one of the 3.7 styles on my site and this is my problem,

User registered and tried going to the user cp to edit settings and the page cut her off in the middle of loading telling her to contact the admin and something about a security token was missing or mismatched

How do I remedy this problem?

This is the style I uploaded -> https://vborg.vbsupport.ru/showthread.php?t=179080

then maybe you should have posted this there?..

Thanks for the sarcasm :)

Though if you looked you would have noticed that I did and didn't get a response, genius.

Questions/Problems regarding custom modifications/styles should be asked in the thread, site or board from which you downloaded it, as they are in the best position to help you.

Reading through the modification's thread it indicates that it is only supported on the third-party site. You may wish to post there in order to receive a response.

If you need to revert and out of date templates then you will need to do so (bearing in mind any modifications to them will be lost). The problem is most likely caused by a missing security token field in the form, you could try locating the forum and fixing it yourself. See the "Template Changes" section of this thread for the code to add.

It seems odd the style was released for 3.7 and is still encountering this error, it must have been overlooked by the author.
