Fatal mistake.

Sorry for my English

One day we had a fatal error with WP-super-cache.
It stopped working the website and it showed a message like this:

WP-Cache Config Sample File See wp-cache.php for author details. */ $cached_direct_pages = array( ); //Added by WP-Cache Manager $wpsc_save_headers = 0; //Added by WP-Cache Manager $wpsc_last_post_update = 1506077718; //Added by WP-Cache Manager $wp_cache_home_path = '/'; //Added by WP-Cache Manager $wp_cache_preload_on = 1; //Added by WP-Cache Manager $wp_cache_preload_taxonomies = 0; //Added by WP-Cache Manager $wp_cache_preload_email_volume = 'many'; //Added by WP-Cache Manager $wp_cache_preload_email_me = 0; //Added by WP-Cache Manager $wp_cache_preload_interval = 0; //Added by WP-Cache Manager $wp_cache_preload_posts = 'all'; //Added by WP-Cache Manager $wp_cache_mobile_groups = ''; //Added by WP-Cache Manager $wp_cache_mobile_prefixes = 'w3c , w3c-, acs-, alav, alca, amoi, audi, avan, benq, bird, blac, blaz, brew, cell, cldc, cmd-, dang, doco, eric, hipt, htc_, inno, ipaq, ipod, jigs, kddi, keji, leno, lg-c, lg-d, lg-g, lge-, lg/u, maui, maxo, midp, mits, mmef, mobi, mot-, moto, mwbp, nec-, newt, noki, palm, pana, pant, phil, play, port, prox, qwap, sage, sams, sany, sch-, sec-, send, seri, sgh-, shar, sie-, siem, smal, smar, sony, sph-, symb, t-mo, teli, tim-, tosh, tsm-, upg1, upsi, vk-v, voda, wap-, wapa, wapi, wapp, wapr, webc, winw, winw, xda , xda-'; //Added by WP-Cache Manager $wp_cache_refresh_single_only = 0; //Added by WP-Cache Manager $wp_cache_make_known_anon = 0; //Added by WP-Cache Manager $wp_cache_mod_rewrite = 0; //Added by WP-Cache Manager $wp_cache_front_page_checks = 0; //Added by WP-Cache Manager $wp_cache_mfunc_enabled = 0; //Added by WP-Cache Manager $wp_supercache_304 = 0; //Added by WP-Cache Manager $wp_cache_no_cache_for_get = 0; //Added by WP-Cache Manager $wp_cache_disable_utf8 = 0; //Added by WP-Cache Manager $cache_time_interval = '600'; //Added by WP-Cache Manager $cache_schedule_type = 'interval';...

To try to solve the problem and access the website with guarantees, via ftp rename the wp-super-cache directory to disable it.

The website ran smoothly.

Today with more time I have been keeping an eye on the subject, which may have failed …
I’m not sure why I’m not an expert in php …

But … curious that the file: wp-cache-config.php contained the following code:

2057 502d 4361 6368 6520 4d61 6e61 6765

Thus until line 343.

My solution, or test to see if it could re-activate the plugin was:

Go to the “wp-cache-config-sample.php” file and copy the code to the “corrupt (wp-cache-config.php)” file.

Well, it worked.

Someone can tell me that it may have happened to re-write the file wp-cache-config.php

And, have I done well with my solution?

Many thanks!!

Miquel.
