An unknown error occurred - no log entry

Question

After copying files from a web server to my local devbox I am unable to open any 'Entries'. I keep getting two of the following error: "An unknown error occured."

The assets section does open and I am able to see the various loaded assets.. This also does not display, same error pop-up.

The strangest part is there are no logs to speak of... I tried clearing all the logs just in case, but they're still empty.

I'm using Laragon with PHP 7.2.11 Apache 2.4.35 and two different sites give me the same error.

EDIT: I have tried ignore_user_abort = On in my php.ini file as per a similar issue

EDIT: The only php error is recurring on every page load, but I thought it was a compatibility thing:

[24-Apr-2019 08:08:02 UTC] PHP Warning:  Use of undefined constant auto - assumed 'auto' (this will throw an Error in a future version of PHP) in D:\laragon\www\cannon-kitchens\craft\config\general.php on line 13

EDIT: I am now seeing some logs, but this appears to be normal operation:

Answer 1

Clear your Cache manually going into the Storage folder. It happens when you add new entries and the code is not written properly or any other issue may reflect this error. So the best thing to clear the storage part manually.

To do this; Delete the entire folder \craft\storage\runtime
