My problem was that the option_value was too long and the constant deletions increased the database size in MB. So first I had to figure out what the database size consists of.
I don’t know your background, so I can’t recommend anything other than asking someone who knows how to code to take a look at it.

I do not agree with @reynierc next statements: “This behavior typically occurs when product information is updated, not continuously.” (It depends on how the website is designed.) and “The increase in the options table IDs suggests that transients aren’t being cleared as they should.” (I don’t know of a way for the code to delete transitions in a way that would reduce the number of ids.). But his answer was of some use to me.

But I agree “It might be worthwhile reviewing if any background processes or cron jobs could be triggering this activity.”. It is also important to understand why a particular transient is being created.

This zip file gives next errors:
Accessing setup page
Trying to get property ‘wpFastestCacheLanguage’ of non-object
Type: PHP Notice Line: 1631
File: /var/www/html/wp-content/plugins/wp-fastest-cache/inc/admin.php

Deleting the plugin
Non-static method WpFastestCache::uninstall() should not be called statically
Type: PHP Deprecated Line: 286
File: /var/www/html/wp-includes/class-wp-hook.php

My questions are:
Is there any reason why variables should be passed by reference?
What are the considerations to insist it?

I do not want to find the source of error i know where it is. I want to know, if there is any good reason why the developer of current plugin might make such assumption? Is there any security considerations involved or might it cause other future errors?

The theme i am using is Hueman and the developer has instructions how to create child theme, but why can’t I use Child Theme Configurator. I am interested of reasons behind the problem nothing else in fear of future. When i choose to use named theme.
