My posts are saving successfully and there is no problem with this error. I just want to know what thing causes this error.

What is your site? :smiley:

my website is only4gamers.ml

Are you using any plugins?

ya many pluging. maybe 10-15.

Usually those errors are related to plugins or a theme normally.

  • you might notice slow loading times or times where your site just will not respond - this is because of rate limiting and using more than 1-2 plugins will only worsen the issue.

Ok. I am going to upgrade my web hosting in few days. thanks.
