Steps to reproduce the issue

Tried to login into Joomla backend as administrator. Got message: "The most recent request was denied because it contained an invalid security token. Please refresh the page and try again"
Now locked out of Joomla.

Expected result

Able to login to Joomla administrator as normal.

Actual result

Locked out of Joomla

System information (as much as possible)

Joomla 3.7.0., PHP 7.0
Website running on a large hosting service.
Server version: 5.5.35-MariaDB-1~squeeze
Protocol version: 10
MySQL charset: UTF-8 Unicode (utf8)
Web server
Apache
MySQL client version: 5.5.35-MariaDB
PHP extension: mysqli

Additional comments

Used phpmyadmin, tbl_extenstions, plg_system_cache and set enable = 0 to disable Joomla plg_system_cache.
Then I could login again as Joomla Administrator. No invalid security token message.
This work-around was found in #9568

The problem is with the system cache plugin and this fix has already been merged for inclusion in 3.7.1

I don’t think “flush cache on update” is a solution as this happen on all forms submit on Joomla 3.7.2 - PHP 7.1— Cause by Cache plugin — Turning it off stop the error (On 2 sites) — Also I got Regular Labs Cache Cleaner that do clear cache on any update in the sites.
It’s evident that you can’t have non-working Contacts Forms until an update is done on the site. Contact forms Have to work 100% of the time.

We have this issue again updating from 3.7.4 to 3.8.3. We tried a lot of times to update to earlier 3.8.x versions, but non worked. So it's still an issue.
