Administrator can't see notes and attachments

[luisinho1973]

Hi there!
MantisBT Version 2.18.0
Schema Version 209
PHP Version 7.0.33-0
Database Driver mysqli
Database Version MariaDB 10.1.48, 10.1.48-MariaDB-0+deb9u2

Suddenly today, me (one of two administrators) can no longer view any notes and attachments, even if I create a new ticket and add a note or file.
When going back to view the ticket or any other ticket notes are not displayed.
Everything else displays as normal, including History at the bottom.
If I go to "Activity" and filter by date, I can see all activity, but can't see on ticket.
The other administrator can see everything ok, notes and attachments.

Of course, no changes, no fiddling. Mantis has been running with untouched configuration for more than three years... but suddenly this.

Do you have the same issue when using the same browser but are logged in as a different user?

Thanks for your comment! Same issue with the same administrator user on three browsers (Chrome, Firefox and Edge), even cleaning cache, cookies, etc. On other PC same issue occurs. No other user has problems, even the other admin user. The permissions and profile are the same on both administrator users.
Thanks in advance,

You can check on a strange entry for this user in the tokens_table. You can simply remove those entries (using phpmyadmin or something similar) and have the user try again.
