DO NOT USE this version of this plugin. It will tell you to upgrade W3TC and if you do, it’ll break the whole site.

Hopefully a new version comes out soon but it looks like people have been having this problem for months.

A2Optimized WP by A2Hosting NOT WORKING !!!

Please i have a “Turbo web hosting plan” with A2Hosting and your much-hyped advertised and payed (because it has a cost, and also costs a lot) A2Optimized site and software accellerator

Use the latest WordPress v4.6.1 with latest PHP 7.0.13 with latest A2Optimized WP v2.0.4

Your “A2Optimized site and software accellerator” it slows down a lot my website and i have this error:

“The following memcached servers are not responding or not running:
Minify: unix:///opt/memcached/run/webcente/memcached-1.sock.
Database Cache: unix:///opt/memcached/run/webcente/memcached-1.sock.
Object Cache: unix:///opt/memcached/run/webcente/memcached-1.sock.
This message will automatically disappear once the issue is resolved.”

Always more than two users here and two months ago they have reported this issue and you not only have not solved the problem, but you have not even answered, you should be ashamed for your very very poor and unprofessional service and support !!!

Continue to advertise and pay us customers a service that is not working your “A2Optimized site and software accellerator” Which also updated very little (On the WorpPress the latest version of A2 Optimized WP is v2.0.4 and you have updated over two months ago and on CPanel the latest version of A2 Optimized Beta is in beta v1.9.11.3 and never communicated the date of the last update).

You have to stop teasing your customers and you have to solve the problem.

I look forward to your response and looking forward to the rest of the problem is solved very quickly because you know them already more than two months.

Slows WordPress Backend + W3TC & Memcached are BROKEN

What a joke! Since the new releases memcached and W3 Total Cache won’t work.
The sad thing is A2 is controlling both the A2 Optimized WP and W3 Total Cache.
In the WordPress backend/dashboard time how long it takes to open the ‘Pages’ menu item.
THEN disable A2 OPTIMIZED WP and retest. Notice that it opens in less than 1/3 the time when A2 OPTIMIZED WP is disabled. What is going on??!!?
A2 doesn’t even mention any of this in their knowledge base. But they have plenty of marketing of how great A2 OPTIMIZED WP, Memcached and W3 Total Cache are worth paying extra money for on their hosted service. What a scam. It seemed W3TC was going to actively developed but its clear A2 isn’t capable.
