I have the same problem with a fresh installation 
:
Raspberry BUSTER,
emoncms 10.1.13
I find this fix for this problem
in the file emoncms/scripts/phpmqtt.input.php , change line 46 from :
‘chdir(dirname(FILE)."/…/…/…/");’
to :
‘chdir(dirname(FILE)."/…/");’
This change fix the problem in my installation.
Ciao.
How did you do the installation?
Making that change will prevent future updates. It will be better to fix your installation than make this change.
Can you click on the button Copy as Markdown next to Server Information on the Admin page and paste here please (no further formatting required).
You seem to have installed the wrong service. It should be the emoncms_mqtt service. the phpmqtt is deprecated.
How did you do the install?
I do this procedure to install emoncms, mosquitto, al some other software necessary in my application in a new BUSTER lite installation. It work well 
( Sorry, new users can only put 2 links in a post… i cannot include all for this reason… )
Set static IP adress
sudo nano dhcpcd.conf
#Example static IP configuration:
#interface eth0
#static ip_address=192.168.0.10/24
#static ip6_address=fd51:42f8:caae:d92e::ff/64

#static domain_name_servers=192.168.0.1 8.8.8.8 fd51:42f8:caae:d92e::1
Start by updating the system repositories and packages:
sudo apt-get update && sudo apt-get upgrade
sudo nano /boot/config.txt

This should be on, or very close to lines 161 and 172 of /etc/apache2/apache2.conf
sudo nano /etc/apache2/apache2.conf
Save & exit, then restart Apache:
sudo systemctl restart apache2
installare EMONCMS :
First, set the permissions for the www directory:
sudo chown $USER /var/www
Firstly we should secure the database server, and then create a database and database user for emoncms to use;
The following configuration commands gives ‘sudoers’ Mariadb root privileges from within the local network, to administer all aspects of the databases and users. It also removes an ‘example’ database and user, which is no longer required.
sudo mysql -e “DELETE FROM mysql.user WHERE User=‘root’ AND Host NOT IN (‘localhost’, ‘127.0.0.1’, ‘::1’); DELETE FROM mysql.user WHERE User=’’; DROP DATABASE IF EXISTS test; DELETE FROM mysql.db WHERE Db=‘test’ OR Db=‘test_%’; FLUSH PRIVILEGES;”
sudo mysql -e “CREATE DATABASE emoncms DEFAULT CHARACTER SET utf8;”
Add an emoncms database user and set that user’s permissions.
sudo mysql -e “CREATE USER ‘emoncms’@‘localhost’ IDENTIFIED BY ‘PWD’; GRANT ALL ON emoncms.* TO ‘emoncms’@‘localhost’; flush privileges;”
Create data repositories for emoncms feed engines:
sudo mkdir /var/lib/{phpfiwa,phpfina,phptimeseries}
…and set their permissions
sudo chown www-data:root /var/lib/{phpfiwa,phpfina,phptimeseries}
Set write permissions for the emoncms logfile:
sudo touch /var/log/emoncms.log && sudo chmod 666 /var/log/emoncms.log
cd /var/www/html && sudo ln -s /var/www/emoncms
Disable serial console boot
sudo nano /boot/cmdline.txt

If you’re using the Pi without a monitor, you can simple turn off HDMI output like so:
/usr/bin/tvservice -o
(use /usr/bin/tvservice -p to turn back on). Add the line to /etc/rc.local to make it permanent, otherwise it will only work until the next reboot.

you can indicate the correct procedure to install emoncms_mqtt service ?
thanks…
I have increased your level so could you post a link to where you found those instructions. They are old and should not be used.
Do you have anything else installed on this RPi? If not then you will be better to start again with the EmonSD image. It is likely there are other issues with your installation which makes helping you very difficult.

This is not a recommended method of installation. You have not installed additional modules, some of the services are incorrect, you have not installed Mosquitto from the apt repo (and that is just what I have found after a quick scan).
I’m sorry, but this is not supportable. If you have issues, you will need to fix them yourself.
Cheers

I’m seeing this too on my installation. I’m on an emonpi running emonSD-03May16. To be fair, I believe this isn’t supported now with the latest emoncms, but I keep this up-to-date myself.
What I’m really confused by is that we have this file:
And in there we have:
chdir(dirname(__FILE__)."/../../../");
require "Lib/EmonLogger.php";
So essentially we can boil the require down to trying to pull in:
dirname(__FILE__)/../../../Lib/EmonLogger.php
But that’s not where that file is in the repo. It is actually in:
dirname(__FILE__)/../Lib/EmonLogger.php
Just looking at the repo on github we can see that.
So how does this work for anyone?
I see that the chdir was changed in this commit:
But I cannot see from that why it would be. scripts/phpmqtt_input.php stays in exactly the same place. So why would we change how to get to the root of the emoncms installation? We’re going 2 levels up from the emoncms installation with that chdir now?
What repositories do you use? ‘up-to-date’ - i.e. you are now on Buster?
That script has been deprecated - emoncms_mqtt is now the maintained script.

Ah i see! Well that is indeed why the chdir was changed for scripts/services/emoncms_mqtt/emoncms_mqtt.php. That needs the extra 2 ../../. But the old one is therefore broken.
I am on the stock from emonSD-03May16 which is jessie. So very old for sure.
It makes sense on the new service though - that explains why new installations don’t have the problem. But should we fix the old one if the script is still there so that people still using that can? Or alternatively, remove the file to indicate it really is no longer supported?
Or alternatively move to a supported OS. Jessie is way EOL.
