Error with Supercache

Hi @philpich

You should edit wp-cache-config.php in wp-content directory. You need to add this on the begin (instead damaged content):

<?php
/*
WP-Cache Config Sample File

See wp-cache.php for author details.
*/

$wpsc_last_post_update = 1504859561; //Added by WP-Cache Manager

In next lines are variables, so you need to keep this part.
until line $wp_cache_debug_log = '';. If you see repeating block, then remove duplicate. So last few lines should be:

$wp_cache_debug_level = 5;
$wp_cache_debug_ip = '';
$wp_cache_debug_log = '';
?>

Don’t put empty space after line ?>.

It’s probably same as https://wordpress.org/support/topic/wordpress-dashboard-no-longer-visible/

I hope that helps.

Hi Saša,

I did not understand what exactly to add! You can give a full example of wp-cache-config.php?

Thanks!!!!

Hi Saša,

I need an example of an already edited file!

Thanks!!!

I am with the same problem in my website, it happened more than 5 times already.

I think it is related with this PHP warning above, since wp-cache-config.php file is being broken with “invalid” characters.

[11-Sep-2017 15:15:37 UTC] PHP Warning: json_encode(): Invalid UTF-8 sequence in argument in /public_html/wp-content/plugins/wp-super-cache/wp-cache-phase2.php on line 53

My last attempt was make this file unwritten changing its permission, nothing happened until now (no error), but I noticed I cannot edit a comment, I got the following msg:

Error: file /public_html/wp-content/wp-cache-config.php is not writable. Error: file /public_html/wp-content/wp-cache-config.php is not writable. Error: file /public_html/wp-content/wp-cache-config.php is not writable.
