Not add functions to the service "joomdle"

Good afternoon
I use
(php 5.65) Joomdle 1.1.3 for Joomla 3+, (php 5.4.37) Joomla! 3.7.2

also I faced an old problem of integration
in moodle I do not see the "Add functions to the service "joomdle""

prompt where to look for an absence reason of functions?
I already on the verge of despair, also doubt that I made a right choice towards integration with joomla.

I will be grateful for any help

Hi.

Joomdle now should add functions automatically on installation, so you don't need to do it.
Was the Joomdle service created automatically? In the screen before adding functions, in the function list, aren't all joomdle functions already listed there?

whether correctly I understand joomdle service?
I have such picture

In the first picture, click Functions. There you should see the list of functions in the service. Please attach screenshot of that page.

I have here such picture. 3 images.
perhaps I can report still my some settings?

I have decided to show process of installation during which there is a mistake. I checked on different joomla. but only on windows server.

Ok, it seems a problem with the installer, as there is a duplicate entry.
To fix it you should be able to:
- Delete the "joomdle" external service
- Re-install (maybe you need to uninstall first) Joomdle plugin in Moodle.
That should create a new web service, and add all the functions to it.

Antonio, you real genius!
Yes at me everything has turned out, I also couldn't present that existence of service leads to such mistake!
I am extremely grateful to you, thanks.

Great, thanks for letting us know. I will try to improve Joomdle installation procedure, to see if we can better deal with the situation you found.
