503 Service Unavailable when "importing content"

Hmm, can't really read the debug log.

What version of GP Premium are you using?

Have no idea why debug file have russian words, when WP using polish :)
I used 1.9.1 GP prem

Is there any way to output the error log in English, or can you Google translate some of it so I can read through it for clues?

Let me know :)

Hope it help :)

Hmm, not sure what's up there. Doesn't look like it should be causing a 503.

I just tried installing Niche on my test server and everything went well.

Are there any other errors in the log?

Nope, thats all what i had..
Mby i can change some of hosting settings, cuz he is blocked "importing content"? http://joxi.ru/D2PBdkysqzYewr

Your settings look ok.

Is WP_DEBUG turned on?: https://wordpress.org/support/article/debugging-in-wordpress/

Is it a completely fresh WordPress install?

Yes, Debug still turned ON http://joxi.ru/E2pkpDni7Mbldm
Today I tried again and get new 2 rows

[15-Feb-2020 09:45:53 UTC] == Start mapping menu locations ==
[15-Feb-2020 09:45:53 UTC] 2 -> 25

Is it a completely fresh WordPress install?

Yes, it was 1st theme to new domain

Mby have some alternative methods to install Niche theme? If need — I can share log/pass from WP or hosting.

Can you try turning off debug to see if it makes a difference?

That log is actually positive, it means the importer is working. That step actually happens after the content import, which is strange.

Login would be helpful. You can send it here: https://generatepress.com/contact

Be sure to mention this topic :)

Thanks!

Debug turned off - it doesn't help http://joxi.ru/DrlOBDMFVOenVA
And shared login/pass :)
