Post installation

I have moved several websites to a new server without issue. I do this by zipping all the files and the database. I amended settings to point to the new database. But the last site gives an error message (see below). The only difference is site size. The DB is around 130MB which has been copied over using SQL splitter software (10 files). Checking the DB gives no errors.  The source files and database backup files have been successfully installed on another server, albeit with a different O/S - Centos 7 whereas the new servers are running AlmaLinux8.

We had to turn on MySQL's general log to satisfy a security requirement. Recently our site was attacked with a zillion bogus requests. 99.99% of these resulted in 404s it caused our disk space to fill up because the general log was recording every query caused by these bogus requests. Why does Drupal do this? 

Is there any way to stop this from happening?

Hi

I use Drupal 10 and of course ckeditor5.
Unfortunately, I do not see the images or videos that I insert in the editor.

However, I see them well in the page.

However, I see them well in the page.
In the editor, I only see the two arrows to insert a paragraph above or below.

In the console I receive the following message:

Hi everyone! I’m working with Drupal 9 and have a question about data transfer between webforms. I’m setting up webforms for a site where we offer demo content with interactive features. I need to automatically update one form after specific actions are completed on another.

 I’m working with Drupal for website, where we offer demo versions of online games. I need to set up automatic updating of one form after certain actions are completed on another form. For example, after a bonus is viewed on the second form, I’d like an automatic message or new element to appear on the first form, displaying updated bonus information.  Both forms are created using Drupal’s Webform module, but they have no direct relationship. I’m using sessions to store data from the second form, but I’m unable to trigger Page load on the first form due to null argument limitations.

Whats the significance of these 'page not found' errors logged by the system? Hacking attempts? Bots? Has my site been compromised, or is vulnerable?
