PHP Fatal error: Uncaught Error: Class not found

Hi I am getting this error when trying to access my admin:

[17-Apr-2020 12:50:26 UTC] Request URI: /lrbits.co.uk/administration/index.php, IP address: 127.0.0.1
--> PHP Fatal error: Uncaught Error: Class 'AdminRequestSanitizer' not found in /Applications/MAMP/htdocs/MYWEBSITE/administration/includes/init_includes/init_sanitize.php:19
Stack trace:
#0 /Applications/MAMP/htdocs/MYWEBSITE/includes/autoload_func.php(48): require()
#1 /Applications/MAMP/htdocs/MYWEBSITE/administration/includes/application_top.php(171): require('/Applications/M...')

#3 {main}
thrown in /Applications/MAMP/htdocs/MYWEBSITE/administration/includes/init_includes/init_sanitize.php on line 19.

I'm using PHP 7.3. Tried 7.1 and 7.2 as well.

I've tried overwriting the relevant files, but still the same. Any ideas?

does this file exist:

admin/includes/classes/AdminRequestSanitizer.php

admin/includes/classes/AdminRequestSanitizer.php

Yes it does

what about this file:

admin/includes/auto_loaders/config.adminSanitize.php

are you using ZC156?

there look to be only 3 files that deal with the loading of the sanitizer. i would compare all 3 versions with the released versions.

you can also turn on the debug autoloading:

define('DEBUG_AUTOLOAD', true);

it is a little tricky figuring out these loading problems, but not impossible.

Yes I am using 1.5.6c, I'll give it another look in a bit and see if I can figure it out as you are right, kit has to be one of those three files but I have already tried overwriting them all with the raw files from 1.5.6c

What about admin/includes/auto_loaders/config.adminSanitize.php that actually has content in it such as:
$autoLoadConfig[0][] = ...

That file was missing. Just put it in and the admin now loads. Thanks very much for that.

i suppose when i asked about that same file a couple of posts earlier, you missed it?
