W3 Total cash … total crash

    Hello!

I′am at the end of my possibilities, as I′m a beginner and don′t have a lot of knowledge about php, webhosting, etc.-

I did an update of my website concerning all plug ins, word press and changed the php version from v7.3 to 8.2

Also I did some edits on the W3 chache plug in, as the site was performing slowly and I thought to be smart to ?follow my instinct“. I guess here is may be the/one point of concernt.

Since then I couldn′t reach the dashboard anymore and received the white screen with a warning message concerning the W3chache plug in:

W3 Total Cache Error: some files appear to be missing or out of place.

Also I received an email by wordpress hinting at a problem with the revolution slider plug in.

According to the forum I tried several things to get back into the back end again, without success.

So here is the list of changes I found in the web, trying to reach for the dashboard:

- I disabled the main plug in folder (FileZilla)

- I tried debug mode, changed it back after failing success

Then I followed the underneath instructions

1. Check .htaccess File (make a backup)
    W3TC will create many directives in the .htaccess file to control the caching behavior. Each section will start and end with comments like “#BEGIN W3TC Page Cache core” and “#END W3TC Page Cache core”.
    Ensure that no residual entries are left over in your .htaccess file after deleting the plugin.
    2. Delete wp-content files and folders
    – cache folder
    – w3tc-config folder
    – object-cache.php (if exists)
    – advanced-cache.php (if exists)
    – db.php (if exists)
    – upgrade folder
    – delete w3-total-cache folder in wp-content/plugins/ (if exists)

Now, I wouldn′t like to reinstall the whole site, as I′m absolutely not experienced in that and I feel quite lost about this…

But I do have a back up of the old version, I just wouldn′t know how to proceed, as ther versions are quite out of time….(?)

Is there any chance to fix this issue by not reinstalling?

Please let me know!

    Hello @ivo23

    Thank you for reaching out and I am happy to assist you with this.

    To confirm, you followed the instructions you mentioned and deleted every file/folder related to the W3 Total Cache and also removed all lines from the .htaccess that are added by the W3 Total Cache?

    Can you please confirm this? Can you please share the hosting provider you are using, and also, since you do not have access to the Dashboard, rename (disable)the plugins one by one in /wp-content/plugins/ folder and see which one may be causing the problem, since the W3TC is completely removed and does not have any impact on the websites?

    Make sure to check the debug log and see if any fatal errors are logged. There should be no need for a backup, or reinstalling the website.
    Please note that most of the plugins are not yet tested up to php 8.2 so you should also try to downgrade the php

    Let me know if this helps!

    Thanks!

    Hello Marko!

    Thanks for your quick reply!

    Relating to your answer here my actions in short form:

    I removed all lines including and between

    “#BEGIN W3TC Page Cache core” and “#END W3TC Page Cache core

    except the following ones (!):

    # BEGIN W3TC Browser Cache …….and following ′till …# End W3TC Browser Cache

    Shall I delete those too!?

    Neither I did′nt delete following folders:

    Wp-admin/maint

    (another forum pointed at this too, I didn′t dare deleting things I can only assume their function.)

    Now according to your message, I renamed (by FZ) any plug in folder in adition to renaming the main plug in folder by ?*_old“.

    OK, I hope it will work, but thank you for replying fastly and giving hope!

    The hosting provider is df.eu (domainfactory)

    Make sure to check the debug log and see if any fatal errors are logged.

    Finally I made it work. I tried to attach the file…doesn′t seem to be possible …I don′t understand this info (‘…’) showing up quite a lot.

    Question(s):

    In wp-config.php it says

    /** Enable W3 Total Cache */

    define(‘WP_CACHE’, true); // Added by W3 Total Cache

    Doesn′t that hint at W3Total chache plug in, that is still active…?

    Attached is the error message by df.eu after recalling the website after your new settings:

    Fatal error: Uncaught Error: Call to undefined function create_function() in /kunden/460109_50678/sites/vm/wp-content/themes/brooklyn/widgets/ut_flickr_widget.php:123 Stack trace: #0 /kunden/460109_50678/sites/vm/wp-content/themes/brooklyn/functions.php(428): include_once() #1 /kunden/460109_50678/sites/vm/wp-settings.php(591): include(‘…’) #2 /kunden/460109_50678/sites/vm/wp-config.php(98): require_once(‘…’) #3 /kunden/460109_50678/sites/vm/wp-load.php(50): require_once(‘…’) #4 /kunden/460109_50678/sites/vm/wp-blog-header.php(13): require_once(‘…’) #5 /kunden/460109_50678/sites/vm/index.php(17): require(‘…’) #6 {main} thrown in /kunden/460109_50678/sites/vm/wp-content/themes/brooklyn/widgets/ut_flickr_widget.php on line 123

    After having reduced the php version to 7.4 the website started showing up in a very deranged mode again…. !

    But log in started showing up in recovery mode, still wasn′t possible though…

    I′m very curious about the next steps!

    Thank you so far and greetings!

    Hello @ivo23

    Thank you for your feedback.

    Yes, you should remove everything from the .htaccess that contains # BEGIN W3TC

    The constant define(‘WP_CACHE’, true); is added to wo-config.php in order for the caching to work in wordpress. This does not mean that W3TC is active, this only means that the constant is defined. You can also remove this as it can and will be added again. Make sure to backup the wp-config.php file.

    If the W3TC folder in the plugins folder is deleted, and all other folders like the cache folder, w3tc-config folder, upgrade folder, and the drop-in files:
    – object-cache.php (if exists)
    – advanced-cache.php (if exists)
    – db.php (if exists)
    it means that the W3TC does not have any impact on the website.

    The error message you shared suggests that the issue is related to your theme, so I would suggest you reach out to your theme support and check with your hosting support also, to resolve these errors. It appears that there was some problem with the theme and the PHP update or similar.

    Let me know if this helps and If you have any other questions.

    Thanks!

    Hello Marko!

    Thanx for your support so far. As youtold me to update brooklyn theme everything seems to be done ands finished. after reactivating all the plug ins it looks like the website should be working.

    But now this should be the start to wok things over and here I′m in trouble again…. I can′t log in to the dashboard …

    Who is in charge of this issue now? It took quite a lot of patience to get through all these steps to get the site back to working … now I′d like to finish tuning content and get things to promotion … ?

    So actually Brooklyn is up to date, as well as all plug ins. I can′t log in to the dashboard, also I couldn′t register the new theme yet … didn′t get it done via FTP ….

    Any advices left ?ChatGPT couldn′t get me any further.-

    Thanx in advance and greetigns Ivo (Uwe)
