WordPress Questions

Hi guys can you help me?

I’m having 502 Bad Gateway in accessing our domain when login.
I’ve already update the codes as suggested from chatgpt but still not working thru ftp.

https://ourdomain/wp-admin/ → 502 Bad Gateway

Hello :waving_hand:

My name is Vladimir.

I don’t see from the logs what is the site in question, but since you are inquiring about wp-admin, I’m assuming this is hosted on Managed WordPress Hosting on Kinsta. As such, you are entitled to use our Support team to help you.

Please open a chat from Mykinsta and the engineer will be there to help :slight_smile:

Kind regards! :waving_hand:
