Easy Web Performance Optimization (WPO) using caching: browser, page, object, database, minify and content delivery network support.
If I could give this a negative 100 rating, I would. First, wouldn't install and had to go through hoops to do so. Then it broke the entire site. I can't get into admin. I am going to have to reinstall wordpress and then use the backup to reinstall the site. Never had a plugin break the whole site. But this one found a way. Will never try it again.
This plugin gets all kinds of rave reviews but over the past couple of years every time I have tried to use the plugin it completely crashes my site. Maybe not right after I install, but after an wordpress update, a plugin update, a different plugin install BOOM! 404s. I understand you can't write code that will not conflict with every plugin, but I have had enough and actually decided to give feedback for once. Hundreds love this plugin and if you can get use out of it great, but from now on I'm going to pass.
Thank you and good luck
Installed this is the two sites i run. And it worked like a charm - for a couple of Days and then i saw i sharp rise in code 403/404. It increased from a handful to hundreds per month. I searched the corners of the web for a solution and have tried a lot of things, but today i uninstalled it. Every time i made a change in something the site worked for Everything between an hour and a couple of Days until it went down.
It seems that the plugin works better in chrome then IE.
And if you want a plugin that works as intended directly when you install it - this is not for you. You have to search and even use some trial and error to máke it work. Right after install my site became 50% slower, but some tinkering later it finally went faster, but then the errors came instead.
Having issues with the cron job - ended up removing the plugin - seems like they are pushing for more paid support from w3-edge.com (plugin's developer) "In response to customer demand, we’ve expanded the offerings around paid W3 Total Cache support. Use the form below to order service and improve your site’s performance today." I'm not sure if the plugin has just gotten more buggy or if the configuration has gotten too complex - but it stopped working for me and a paid support modal dialog appeared on the plugin page.
Nothing is working as expected. NOTHING.
And as soon as you have spent days of you life digging in the code, he changes something and: the actual file resides in wp-content/cache/minify/000000/34c4b/default.include.js but browser requests /wp-content/cache/minify/000000/34c4b/default.include.4b1194.css
Congratulations! You are served. Another heart atack and another day went for nothing. [abusive comment removed]
There is no walkthrough to set this plugin up properly -- I had to do a search in YouTube to find a tutorial that would help.
Between enabling the CDN (I use my amazon cloudfront account) as well as minify took my speed from 6s to 44+ seconds ... UM NO.
It did have me an A grade using GTmetrix and a 94 in scoring with PingTools but my blogsite loadtime was HORRENDOUS!!! How I got an A and 94/100 with a 44 second speed, I haven't the faintest o.O It's quite perplexing.
This plugin is NOT userfriendly unless you are VERY WELL versed in caching and how it works. I would say it sin't not a even good for advanced users if you don't know what you are doing.
I'm very sad because my hosting company recommended this caching plugin after 2+ months of hell -- and it still has not helped my blogsite in any way, shape or form. It's only made it worse.
It does not play well with many plugins and it doesn't play well with my current theme. I am not going to stop using my plugins that I have used for 2+ years for a caching plugin that obviously is causing MULTITUDE of issues for many on a DAILY basis -- and the there just doesn't seem to be ANY response for the authors.
Deactivated, deleted and moving on!
I´ve used W3 Cache Plugin once, but it is too much complicated, and made my site felt down, so i put in the garbage the plugin by FTP, my site come back, but could not acess my wp-admin, so ihad to put the plugin again to try acess my wp-admin. I´m not sure if it will work, or i have to backup mu website soo bored! Because this i not recommend W3 Cache. Prefer use Google Speed Service.
Brought my site down - admin and front-end. Could not even un-install it. Had to rip it out by hand via FTP and mySQL database.
Don't bother installing it.
Just after update to version 0.9.2.10 got the error msg - "Minify Auto encountered an error. The filename length value is most likely too high for your host. It is currently 150. The plugin is trying to solve the issue for you: (solving ...)...
My site runs on the latest version of WordPress on a dedicated CentOS server running Apache and PHP through FastCGI. The previous version of W3TC was brilliant and did a fantastic job of minifying and caching through Opcode APC caching. Since upgrading, NOTHING works. I get a constant "Minify Auto encountered an error. The filename length value is most likely too high for your host. It is currently 150. The plugin is trying to solve the issue for you: (solving ...)" error every time I enable minifying and, even when I switch to manual mode and configure it all that way, NOTHING is minified. I have tried APC and disk caching methods and have played around with the filename length values to no avail. I am now forced to use an alternative, inferior minify and caching plugin because W3TC simply will not work anymore.
