Varnish / Varnish won't work
« on: May 12, 2019, 05:45:53 AM »

Hi there,

I'm hosting quite a few websites on my server. I have only one site which is approved to be using varnish with - all other won't, although I've set them the same as the one which is working, as per the attached screenshot.

Any idea what might be wrong?

Addons / netdata installed by itself???
« on: April 30, 2019, 05:11:23 AM »
Hi there,

I'm running CWP7pro and yesterday I've noticed there's a "Graphs" entry in the menu, which I didn't notice before.
I clicked it and there was a sub-entry named "netdata". Clicking it actually resulted in nothing. I mean, there was no data showing except for the headline "netdata".

BUT! Ever since I'm being bombarded with emails from netdata and have noticed a high resources usage. Checking the processes running, I see many netdata processes (/usr/libexec/netdata/...) so I went checking this folder and indeed its date is of yesterday at the time I've accessed this sub menu.

A. How do I uninstall this ASAP?
B. How come it was installed without asking my permission???

I'm totally pissed off currently. Would appreciate a prompt solution please.

PHP / Error 503 for WordPress on PHP-FPM 7.3.4
« on: April 29, 2019, 05:29:09 AM »
I've built PHP 7.3.4 and configured a test wordpress site webserver to use it but I get a 503 error.
I've tried with other sites - and the same result.
I've tried disabling plugins, but the error is still there.

Anyone managed to run Wordpress on PHP 7.3.4?

PHP Selector / Do I need both php selector and php-fpm selector?
« on: April 24, 2019, 03:54:10 PM »
Do I need to build PHP and PHP-FPM versions or can PHP-FPM be enough?


I'm using a VPS on Hetzner, and am trying to force wordpress using SMTP to send emails.
Of course I've created a mail address and it's working fine with non secure connection (port 25). I can even connect to the smtp via SSL from outside the server (tested with 3rd part test sites), but when configuring Wordpress with plugins like WP Mail SMTP I'm getting an error.

I just don't want to reveal my domain, so I've change my hostname to and domain to I've also hide the full IP.

The problem that I believe I'm facing is that the site is presented as Why is that happening?

Here's the log:

Apr  9 19:59:10 cwp postfix/smtpd[5488]: connect from[]
Apr  9 19:59:10 cwp postfix/smtpd[5488]: SSL_accept error from[]: 0

And here's the log when I'm trying to send an email from a 3rd party site to my gmail via the same smtp account:

Would appreciate any help!


I've got the following mail from the firewall. Any idea what it means? I didn't see anything odd and the site is loading.

PHP / Changes in PHP.INI won't work!
« on: February 05, 2019, 08:16:55 AM »

I'm using CWP PRO and my server is configured to use NGINX+APACHE+VARNISH+PHP-FPM, and I was trying to increase upload_max_size for a user. I've tried the following:
1. Adding a php.ini file - didn't work.
2. Editing php.ini within the user's CWP panel - didn't work.
3. Deleting php.ini caused the panel to create a default php.ini, yet - didn't work.
4. I've found an answer here that since we should use .user.ini instead of php.ini - didn't work.
5. Putting this .user.ini in wp-admin folder - didn't work.
6. Putting php.ini in wp-admin folder - didn't work.
7. Another answer here said something about a trailing slash after localhost - but mine didn't have this slash.

So... why do we have to guess? Why for instance the definitions for php.ini the user sets in his panel won't work. Even the definitions under PHP Settings -> PHP Simple Editor in the main CWP panel won't change anything.

I'm really puzzled where I can change this php settings either globally or per user (preferably per user).

Mod_Security / Hugh log files!

I just found that my mod security log file was 4GB large!!!
Is there a way to limit this log?

Apache / Large domlogs files

In /usr/local/apache/domlogs/ I have very large log files. Is there a way to make them up to a specific size?

Mod_Security / Changing rules on Comodo WAF with CWP Pro
« on: December 10, 2018, 06:00:08 AM »

I've just got my CWP Pro enabled and installed Comodo's WAF but I need to disable some rules. Where do I do that?

Aplications / Wordfence / Ninja Firewall
« on: December 09, 2018, 06:14:36 PM »

Since the update to PHP-FPM I can't install Wordfence or Ninja Firewall (both are using auto_prepend_file) on my wordpress sites.
My webserver is apache + varnish + php-fpm. I've also tried changing the webserver to use fastcgi, but it didn't change anything.

Any idea?

PHP / Can't use personal php.ini
« on: December 06, 2018, 04:15:47 PM »

I was going through this guide, but couldn't make the persoanl php.ini (per account, and not a global one) to work.
By the way, I beleive it was working properly before I upgraded to php-fpm yesterday.

Would appretiate if anyne can advise what I might be missing.
By the way, during the php-fpm upgrade, I was also compiling some other php versions. Might this cause such an issue?


Installation / Login loop prior to CWP update
« on: December 05, 2018, 11:39:33 AM »

As most of you I was prompted to update CWP to PHP-FPM. I tried. But once I clicked the next (?) button, I got into a loin loop.
CWP is asking me again and again to login. I'm inputting my credentials, the dashboard loads and immediately asks again to login.

Any idea?

Informations / Spam on this forum
« on: September 20, 2018, 05:36:03 AM »
I hope this is the right place to post this. Couldn't find a specific forum which is only related to CWP forum itself.
Anyway, lately there's a lot of spam posts, and while I'd like to report them to the admin, there's a limitation of 120 second in between reports, which makes it really hard to report when there's so many spam like today...

Would you consider reducing the report gap to something like 15 sec?

Aplications / NetData vs Glances
« on: September 20, 2018, 05:30:24 AM »

Did anyone try to install Glances along side to CWP?
How is it compare to Neddata?

Here's the installation guide for Glance I've came across accidently.

Important note: I didn't install Glances, hence can't say if it works well with CWP.
