Thank you so much for solving the problem.

Then, another question, also on the display of time.
If you choose an alternative option - how much time has passed since the publication - then I get a strictly English version, despite the fact that I use a Russified file. It's not in a hurry and not critical, but I would like to figure it out. It seems that the data is taken from some other file. I replaced these lines in the same way in the English source files - but the English text is still output.
Maybe you can tell me where it can be corrected.

Also, when installing the Russian language, the part for the site breaks a lot and is not displayed correctly, there are lines with errors.
I can later upload the russified files for part of the site (now I use the version from RC that I personally translated) - everything works fine with it.
Later and for the admin part.
If necessary of course =)

You're most welcome.

I think you have to share with us which part is not translated to Russian language translation so that we can investigate this issue.

It would be helpful if you can update some screenshots regarding this.

After installing Russification, this is how the activity module looks on the main page


It should be like this


After my translation, everything looks quite correct, except that there is no way to translate some lines.
For example, in the sort menu.
And when choosing to display the time since publication. Marked on the screenshot.


p.s.
After correcting the time zone in the comments, everything is fine.
But in the Activity module on the main page, the time lagging by 3 hours is still displayed.

The attachment contains files with acceptable Russification for the Site side

Try translate this language constants from the following file on your site and see how it goes.

COM_KT_SORT_MOST_LIKES="Most Likes First"

JoomlaFolder/administrator/language/ru-RU/ru-RU.com_komento.ini
JoomlaFolder/language/ru-RU/ru-RU.com_komento.ini

Regarding the lapsed time, the original language constant from this file JoomlaFolder/language/en-GB/en-GB.lib_foundry.ini so you can duplicate this file then put it into this file location JoomlaFolder/language/ru-RU/ru-RU.lib_foundry.ini

Thank you.
The proposed methods of correction have completely worked.

The last problem remains at the moment.
Module: Komento Activities - still outputs time lagging behind my local time.
Please tell me where it can be fixed?

You're welcome.

Can you try to download my attached file then replace it with the following file location and see how it goes.

JoomlaFolder/administrator/components/com_komento/includes/comment/comment.php

Thank you.
Now the activity module outputs the correct local time.

You are most welcome. Glad to hear that your issue has been resolved now.
