1) Yesterday, at my request, my hosting moved the site to another server. However, the problem arose again.
2) The problem occurs when I update (edit and republish) any published post. It does not appear when editing an unpublished post, or publishing a new post, or just editing a published post.
3) The problem occurs whenever and for which post I do the above operation.
4) Whether the post is long or short does not change the occurrence of the problem.
5) The problem also occurred when all plugins and themes were inactive, and switched to twenty twenty-two theme.

I am tired and hopeless.
I guess there’s not much left to do anymore.
Both my friends here and my hosting were very interested.
Thank you very much everyone.

@bcworkz , I did not revert to 8.1…. I used the Query Monitor plugin. There were no unusually long queries.

@alanfuller , Site is live but we have not a lot of visitors in spikes.

@otto42 , After downgrading to 7.4.3, the deprecated lines disappeared, but the problem still occurred.

Throughout this issue, my hosting company was really involved and gave me the following support (they said that):

1) We did not encounter a process that received an error or stuck.
2) There is no abnormality in CPU and ram consumption on your site in general.
3) We have optimized your database.
4) We increased your PHP limits.
5) We have provided an extra resource definition in your hosting package.
6) When we provide a review, the main problem here may be that the data going to the database hangs and goes into sleep mode. This indicates that the queries are incorrect or that the queries made by your plugins are causing the error. The site starts live when the SQL service is restarted. At this point the problem may be sql queries. In general, we recommend reviewing your database queries.

First of all, thank you everyone.

I want to answer it first, especially since you all are asking the same question:

About 1-2 hours ago, I repeated the following two things.

I installed and activated the Health Check plugin; I did the text editing and republishing process again; and the 503 issue occurred again.

Next, I deactivated all plugins (definitely all) and the theme (switched to the twenty twenty-two theme); I did the same process again; and the 503 issue occurred again.

At the time the error occurred, no error lines were generated in any of the error/debug files in the public_html, home directory, and wp-content folder.

Hi @macmanx

I dropped back to 7.4.3 and the problem appeared again.

8.1.21 (supports 64-bit)

Sorry @macmanx . You are right. Thank you very much!

I forgot to add this note: My third update was on July 24, 2023 at 11:41 am, and then error 503 appeared. At the same time the debug.log file is stuck with the warning:

[24-Jul-2023 11:41:28 UTC] PHP Deprecated:? htmlspecialchars(): Passing null to parameter #1 ($string) of type string is deprecated in /home/meslekh1/public_html/kokdizin/wp-includes/formatting.php on line 4650

At the time, there were no errors or warning notes.

Hi @macmanx

Today I generated the error by editing and republishing the same post three times in a row.

The first two republishing went smoothly. But after the third republishing the 503 error appeared.

You can find the debug log here.

Hi @macmanx

At this time, I tried again by deactivating all plugins and theme and the problem reappeared as well.

Hi @macmanx

I contacted my hosting. I reproduced the issue, and at this time they investigated the issue.

They sent me this screenshot and they said: “This process shows that the queries are incorrect or the queries made by your plugins cause an error. When the SQL service is restarted, the site broadcasts. At this point, the problem may be sql queries. In general, we recommend that you provide a review in your database queries.”

What can I do now? Thanks..

Hi @macmanx

Unfortunately the problem has not been fixed. ??

1) I downloaded the latest version of WordPress to my computer.
2) I connected to the server via FTP.
3) I deleted the server equivalents of the latest version wordpress files (except wp-content, config.php, htaccess and favicon).
4) I have uploaded the latest version files to the server.
5) I cleared all cache.
6) I edited a published post (added a question mark to the text) and said save.
7) The post was saved, but when I wanted to do the same operation in another post, when I said save, it did not complete the process and gave a 503 error.
8) The error fixed itself after a very short time.

Hi @macmanx

I followed your all suggestions, but the problem still reappeared.

Hi @raytan12

I am not using any page builder plugin. I don’t even use Gutenberg as I find it confusing and too detailed, I use the classic editor plugin. I edit pages with my theme’s template possibilities.

Yes, i clear.

and now the problem is gone.

Thank you for your kind and quick support @rogierlankhorst ??

@rogierlankhorst Thank you for your support. Is this a serious issue and when we say “temporary” we mean an issue that can be fixed in how long because the issue still persists?
