Miro Soares on "W3 Total Cache "You do not have sufficient permissions to access this page""
Hello guys!
I hope any of you can help me out...
After installing the Live Composer Page Builder I've got thus message: "There is a problem in W3 Total Cache plugin settings that can break your page builder. Luckily, it's easy to fix it."(with a link in "easy to fix it").
But when I click in the link (or when I try going directly to W3 total cache settings) the page doesn't load and I get the message "You do not have sufficient permissions to access this page".
I have searched on the forum and found around 4 or 5 topics. Most of them talks about changing the prefix in the database. I am not sure if this would be the case, since I only have this problem when I go to W3 Total Cache settings. To access all the other plugins works fine.
I have tried to uninstall and install the plugin again. It didn't worked.
Does any one have any idea on how to fix it?
I would really appreciate any help.
Thank you.

mattjamesaus on "[Plugin: W3 Total Cache] Memcache Collisions"
Hi Guys,
I've noticed that when i have two versions of the same theme (with different URLs sharing the same memcached server that occasionally it appears that the set and getting of objects is somehow getting mixed up between the two sites resulting in gibberish.
Is there some way to add a unique prefix to the keys generated in W3TC so i can share the same memcached server between the two sites?

reneses on "[Plugin: W3 Total Cache] Cache-Control header for S3 uploads"
Hi!
It would be great if you would include an option allowing the user to specify custom headers while uploading files to Amazon S3.
In my case, I would like to set the Cache-Control header for all the images that I upload. According to this link that can be easily done by adding a header in the PUT request:
PUT / ObjectName HTTP/1.1
Host: BucketName .s3.amazonaws.com
Date: date
x-amz-meta-Cache-Control : max-age= <value in seconds>
Authorization: signatureValueDo you have anything like this planned for the near future?

sporbillis on "[Plugin: W3 Total Cache] Cached for logged in users"
Hello,
I am facing a problem with the caching with my logged in users which when they are on the homepage after they log-in they appear logged out but if they click on any of the categories they appear logged-in. This happens to the admin aswell.
I have set the plugin 100% and i have set it to NOT show cache pages to logged-in users.
After an extensive research in the forums i couldn't find any solution.
Maybe someone here can help?
Please reply.
Thanks

arxeiss on "[Plugin: W3 Total Cache] Bug? - Not removing Page cache"
I found, that TTL of Page cache is the same as Expires header lifetime in Browser cache. But even I set only 120s, file is not invalidated.
If I have own page and in template for that page I'm selecting some posts types, after update this page is not invalidated - I found this is normal behavior, but after those 120s I would like to see those changes.
Is it bug, or there is some minimum TTL and 120s is less than that?

dedicationgraphics on "[Plugin: W3 Total Cache] Woff2 CORS header MaxCDN"
We have custom fonts on our site and it seems that regardless of our settings on the CDN tab the W3TC CORS header is always:
<FilesMatch "\.(ttf|ttc|otf|eot|woff|font.css)$">
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "*"
</IfModule>
</FilesMatch>
We're missing FilesMatch WOFF2 and it's being blocked when the CDN is active. We could optionally set the CORS header in MaxCDN but we can't seem to find a way to stop W3TC from re-adding the code above. Please advise.

Hi,
I have set Garbage collection to 86400s but if I connect to my server via ftp, .old files are still there from the first day. This only happens with minify files, not other caches.
Do I need to remove .old files manually via ftp?
Regards!

Chris Whiteley on "Does Cron Frequency Impact W3 Total Cache?"
I have my WordPress crons set up as server crons, and yesterday my host suggested reducing the frequency of the crons. They were changed to run once per day. Since that time my site has started running extremely slow.
The site was previously running at a good speed using W3 Total Cache, but now it has moved to a crawl and often times out.
Would reducing the crons to run once per day have an impact on W3 Total Cache's ability to keep the site running fast?

memcache doesn't work on PHP7, we need to use memcached which isn't supported by this plugin.
It would be great if memcached support could be added.

amfriedman on "[Plugin: W3 Total Cache] Bug: wrong warning in the admin"
Hi folks,
This plugin gives me a warning in the admin that says:
"The Database add-in file db.php is not a W3 Total Cache drop-in. Remove it or disable Database Caching. [Remove for me]"
This warning is a false positive. It is reacting to a file db.php that was placed in the /wp-contents/ folder by a different plugin: Query Monitor. The db.php file is necessary for that plugin to provide me with deep diagnostic info about database activity. W3 Total Cache should ignore this file and, frankly, should never interact with files in the root of /wp-contents/.
