I found more problems when I tried to delete the directory. It then caused more issues. So a complete uninstall sequence:

To disable dodgy W3 Total Cache:
1. I went into the Database and disabled the plugin in the Options table, active_plugins field. That brought the Plugins screen back.
2. Delete dir /plugins/w3-total-cache to w3-total-cache.
3. In .htaaccess, remove:
# BEGIN W3TC Page Cache core
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP:Accept-Encoding} gzip
RewriteRule .* – [E=W3TC_ENC:_gzip]
RewriteCond %{REQUEST_METHOD} !=POST
RewriteCond %{QUERY_STRING} =””
RewriteCond %{REQUEST_URI} \/$
RewriteCond %{HTTP_COOKIE} !(comment_author|wp\-postpass|w3tc_logged_out|wordpress_logged_in|wptouch_switch_toggle) [NC]
RewriteCond “%{DOCUMENT_ROOT}/wp-content/cache/page_enhanced/%{HTTP_HOST}/%{REQUEST_URI}/_index.html%{ENV:W3TC_ENC}” -f
RewriteRule .* “/wp-content/cache/page_enhanced/%{HTTP_HOST}/%{REQUEST_URI}/_index.html%{ENV:W3TC_ENC}” [L]
</IfModule>
# END W3TC Page Cache core
Then upload this file to root.
4. Rename files /wp-content/advancedcache.php to advancedcache.phpBADD and objectcache.phpBADD

I think I solved the problem. I went into the Database and disabled the plugin in the Options table, active_plugins field. That brought the Plugins screen back.

I deleted a:2:{i:1;s:37:"social-media-widget/social-widget.php";}

In fact, i deleted i:2;s:33:"w3-total-cache/w3-total-cache.php";

Hi there,

I have a similar problem. W3TC has stopped my Plugins directory from loading, so I cannot deactivate it.

I tried commenting out line 127:

w3_wp_request_filesystem_credentials();

But that did not work? Any ideas?

Thanks for the efforts, it didnt work.

Ok I am inserting the code into the post, e.g.
[php] require(‘https://www.example.com/example.php&#8217;); [/php]

Saving, then going to the frontend, refreshing and then checking the source code. It is still stripped out from the post.

Hmmm, that did not work. The plugin was installed, but I still could not include that external code. Any ideas?

I have discovered that the post strips out the php code, so I am trying out the plugin https://www.ads-software.com/extend/plugins/allow-php-in-posts-and-pages.

I discovered that as well. I have found a jquery plugin that has cross-browser support. Many thanks for your reply.

Many thanks for the reply, will do.

I discovered it was a MOD_reviwrite issue. I contacted the domain hosting company who bypassed the rules from the website, that curred it.

I have fixed the issue. I contact the domain hosting company. It was a MOD security problem. In the end, the rules were bypassed which triggered for my domain.

Thanks for your help.

Yes I did – carefully as well. I found an error in logs:

Is this a possible MOD_Sec issue?
