Easy Web Performance Optimization (WPO) using caching: browser, page, object, database, minify and content delivery network support.
I was really pleased when I put this plugin on my site - the Google PageSpeed response was better than with any other combination of plugins. And then I checked on a variety of browsers - and the only browser that rendered my site properly was Chrome. To cut a long story short, the problem is isolated to page cache setting - all is well when it's deselected! Which is not much use because that's where I got all the pagespeed improvements. When W3 is active and page chache is active, IE,Safari and Firefox only render the header and footer of my site. All else is missing!n It's a shame - this seems like a superb plugin!
Ho installato questo plugin su un multisite e mi è apparso internal error 505.
Oltre non vedere più il sito non riuscivo più ad entrare in wp.
Dopo che l'ho cancellato sono continuati i problemi, neppure facendo il backup del sito ho risolto nulla. Ci sono voluti 3 gg con il supporto dell'hosting... panico!!!
Couldn't get this to work with my WPZOOOM theme.
It did provide the messages below but this is too concise for me to feel confident I might try and follow it without ending up in a mess.
FTP credentials don't allow to copy to file /home/sites/bloxham.info/public_html/broadsheet/wp-content/advanced-cache.php
Please execute commands manually
or use FTP form to allow W3 Total Cache make it automatically.
I paid $250 for their theme optimization package about 3 weeks ago .. and still haven't heard anything. They aren't responsive via email or phone. I've asked for a refund .. to no avail. I hope mine is a one-off & other people have had good experiences.
After living with this plug-in for 2 years through all the broken upgrades, bugs, and general frustrations, the conclusion is that I am returning it to sender. Why - for the last 3 years I have been blaming slowness on HostGator. I just finished upgrading to a VPS. Although the speed of my blog improved on the VPS, it was still on the order of 4 seconds. With the uncertainty of Hostgator gone, I decided to disable W3. Guess what - the speed improved to 2 seconds. WTF. Its clear that this plugin is either too bloated to compensate for any its puported improvements, or that is has some other big problem. I suggest that you try one of the alternative caching plug ins; when I did, my site speed improved to less than one second. And if you are paying the developer of this plugin for troubleshooting help, I suggest you request a refund for all the beta testing you are apparantly doing for him.
W3 Total Cache is what I call SLOPPY SOFTWARE, when you deactivate it and then delete it you might reasonably expect it to be removed, but NO, all sorts of remenants are left on your site.
Why is this important?
Well if you want to be able to migrate your site here are some issues, deactivate W3 Total Cache and run backup plugin (leaving it on screws will any of them).
Migrate the site to a Dev subdomain and try to delete and re-install W3-total cache. FAIL - 404 error
So go have a look at your site with FTP and find loads of W3-total cache files left behind, so you rename them and try to upload W3-total cache again, FAIL. 404 error
Well you could try and upload the plugin manually but by this time I am so p'ed off that I am going to install WP Super Cache.
I have had W3-total cache break sites when wordpress updates in the past so I have never trusted it, this experience was on a client site.
What W3-total cache need to do is put in an uninstall routine that REALLY does uninstall all files and nukes all W3-total cache database tables when you uninstall.
As I said SLOPPY SOFTWARE
This plugin totally messed up our site, things went missing eg pics, the site actually loaded slower and it actually stopped anyone from adding a listing or photos to the site.
It also messed with the FTP with us not actually being able to back up the site so we had to rely on our webhost to restore the site!
We had been using this plugin for a few years.
After the latest update, it broke our site layout on the sites we updated on. When we deactivated it, it wiped out our site entirely. We had to reinstall from a backup and I had to pay our programmer 3 hrs work to remove it manually and fix our database from where w3 cache had corrupted it. In all this plugin has cost me about $200.
This almost cost us two big clients as well. We have since removed the plugin from ALL of our sites. Lesson learned I guess.
Just sharing our bad experience to help others. This is all factual so it is what it is.
I fought with this plugin for almost two months. After many attempts I could not get any satisfying result and indeed my site has become very slow.
However I have not given a low rating for the performance of the plugin, but because no one answers my support request sent ONE MONTH AGO. Indeed, it seems that someone has fun delete my messages aimed to update the situation.
In conclusion, I do not like the "atmosphere" that envelops this plugin.
This plugin is not only overly bloated (7.13 MB) but doesn't work as well as some of the other less bloated cache plugins like Quick Cache.
VERY IMPORTANT- Do not try uninstalling this plugin as it will cause an error on your wp admin panel and you wont be able to log back in without re-uploading the plugin and renaming a number of files. Simple put....a pain in the A$$. This plugin really doesn't deserve to be located in the wordpress.org plugin page.
