Compile Error stopping access to Dashboard : Symfony\Component\Debug\Exception\FatalErrorException:

[motley6]

I have a little online shop which has been running for about 10 years. Currently: Prestashop ver: 1.7.8.11, PHP: 7.1, no updates or changes in at least 6 months now - I work on the notion "if it ain't broke, don't fix it".

The shop appears to be working fine, but out of the blue, as of Thursday (I think?) last week, I can't access the dashboard/backend, and get the following error messages when I try:

Compile Error: Declaration of PrestaShop\Module\PsAccounts\Vendor\GuzzleHttp\Psr7\Request::withRequestTarget($requestTarget) must be compatible with Psr\Http\Message\RequestInterface::withRequestTarget(string $requestTarget)

FatalErrorException

Any ideas on fixes please? I'm a businessman, not a coder, and suspect it is probably something simple which I'm just missing. Thanks in advance.

Hello, first try renaming the ps_accounts folder to ps_accounts_tmp, as this module returns this error.

There are probably some changes on your server.

Maybe they updated php

Folder path:

/modules/ps_accounts

Check if the hosting has not outsourced PHP 7.1.
Some hostings get rid of the older versions, that forces you to update with errors or move.
