Issue Additional configuration directives in PHP Settings are overwritten during a service package synchronization

[S. Schröder]

If we make any changes in the PHP Settings in the Additional configuration directives field, as explained here:

https://support.plesk.com/hc/en-us/articles/360005366713-How-to-manage-PHP-max-input-vars-variable-on-Plesk-for-Linux-

Then they will be overwritten at the next service pack synchronization.

In my eyes a bug.

Am I right or is this only with us?

With kind regards,

This is not a bug, but correct behaviour. Plesk synchronizes the settings of the service plan with subscriptions. And if these custom parameters are not specified in the service plan PHP settings, then they will be the same as they are defined in the plan. Therefore, you need to add these Additional configuration directives to your PHP service plan settings.

Sorry, but that makes no sense at all. And the above article then also makes no sense. I can then never make a subscription related change if it is overwritten/deleted again at the next sync.
I want to set exactly as described in the article for ONE single domain max_input_vars = 5000. I do NOT want to set this for all domains of this service plan.

With kind regards,

You can add an Add-on plan with the needed PHP setting max_input_vars = 5000 and then go to subscription of this domain, click "Change plan" button and add this Add-on to this subscription.

How does this work?
Add an add-on and copy the php-settings from the original service plan and add the max_input_vars to the "Additional configuration directives"?

The docs are not really helpful:

Setting Up Add-on Plans

Add-on plans extend the amount of resources and services provided with a subscription (for example, additional gigaby...

Yes, thats the way to go
