XF 1.4 Unsubscribe from watched thread / email link not working

[Gambleru]

Somehow the links standard forum notification emails, which have 2 links at the botton: to unsubscribe from thread or to stop receiving emails from forum entirely - both do not work.
1st in the form of http://*****.com/forum/index.php?watched/via-email&u=805&a=no_email&t=thread&id=13197
2nd in the form of http://*****.com/forum/index.php?watched/via-email&u=805&a=no_email

Both get the following error: This link could not be verified. Please try from another link.
I've searched this forum and haven't found either same problem or a solution.
Any ideas, anyone?

Thanx

Those links appear to be missing the verification string.

Do you have any add-ons installed? Any outdated phrases/templates?

addons

Outdated templates: some, probably, but the users getting the error are not using them, main template is SoftResponsive by Artodia, updated together with 1.4.3
Outdated language files: unlikely

Those links appear to be missing the verification string.

How do we add/fix one?

Have you edited any of the php files for any reason?

Is it some users or all users?

Please reupload all files and go to <url>/install/ and rebuild the master data. Please also disable all add-ons and test with a completely default English language (if you're using a translation).

Based on the code, I don't think this is possible. There should always be a value for that.

Nope, we have not.

It is the same for all users, will try to implement suggested fix and update on the status asap, thanx, Mike & Brogan.
