Issue Error loading php-info

[omexlu]

Hello,

I have the problem in Plesk that the php-info of a subdomain can not be loaded, all other domains/subdomains under the same PHP version can be called without problems.

That's really strange, what could be the reason?

Thanks in advance.

* What happens when you try to load the page? Any error messages?
* What do you see in error_log?

* What do you see in error_log?

I try to open it from the panel and I always get an error message that it cannot be loaded even after few trys.

Which error.log where should I look?

The problem occurs only with a certain subdomain, all others work.

 

[Monty]

Well, but what is the exact error message you get? Did you check DNS? Are you able to load static HTML pages from that subdomain?

The error log is in /var/www/vhosts/system/<your.subdomain.tld>/logs

Everything works as it should, except that the php-info in the panel for this subdomain cannot be called.

DNS & everything is correct, everything else is working but the php-info in the panel:
Error: Unable to retrieve information about the PHP configuration.

There is nothing in the mentioned error.log, because the problem is with being somewhere in the panel and also must being another log.

 

[Monty]

Error: Unable to retrieve information about the PHP configuration.

That's the info I was looking for.

Check this: Unable to open phpinfo() in Plesk: phpinfo() has been disabled

 

[omexlu]

I have researched all this and it is not, phpinfo is not disabled.

The settings are the same as for all other domains, only here it cannot be opened.

Outside of the plesk-panel I can also view the php-info.

EDIT: I found this in ''/var/log/plesk-php74-fpm/error.log':
[09-Mar-2020 10:00:29] WARNING: [pool adserver.domain.tld] child 20131 said into stderr: "ERROR: Unable to set php_value 'disabled_functions'"

Maybe there is something wrongly defined here, I'll have to look later.

 

[Monty]

Hmm, does it really say "disabled_functions"? If so, then you have an error in your (custom?) php.ini settings, as the function is called "disable_functions", not "disabled_functions".

Can you post your file /var/www/vhosts/<your.subdomain.tld>/etc/php.ini?

 

[omexlu]

that was my error has that in the additional statements misspelled, this error message is now already gone, anyway, I can not call the php-info of two subdomains over the panel.

Can you post your file /var/www/vhosts/<your.subdomain.tld>/etc/php.ini?

This file does not exist here.

 

[Monty]

This file does not exist here.

Sorry, I meant /var/www/vhosts/system/<your.subdomain.tld>/etc/php.ini

Here is the content of the php.in the affected subdomain

Looks OK to me.

Do other PHP scripts on the same subdomain work or is it just the specific one with phpinfo(); ?

Have you already tried switching the PHP handler to another version and switching it back to the original one again?

Everything works as it should only that in the panel the phpinfo can not be called, but in the script via browser it works.

No I haven't tried that yet, but a second subdomain is affected and 5.6.x still runs on it.

@IgorG
is such a problem already known, or what could I do?

thanks

Ah, so you only can't open the link "View the phpinfo() page" in Plesk? For the whole time I thought you can't open a PHP script in your browser that contains the phpinfo() function call....

Meh, in that case: Check your /var/log/plesk/panel.log and /var/log/sw-cp-server/error_log files and check if you see any errors reported there.
There used to be a bug in Obsidian that was related to the phpinfo link in Plesk, but that bug has been fixed long time ago: [FIXED BUG] phpinfo() page in Plesk does not open when SEO-safe 301 redirect is enabled: Unable to retrieve information about the PHP configuration

Is you Plesk Obsidian installation up to date?
Have you ever tried plesk repair web?

No problem Maybe it's my bad English.

Yes, all is up-to-date

Not at this, should i do this? And how?

EDIT:
I think I got it:

Both subdomains are currently protected by htaccess on the DocumentRoot, so phpinfo cannot be accessed in the Panel.

I have to try later when I am at home.

Ah yes, this is crucial information: You won't be able to load the "view phpinfo" link in Plesk if there is a password protection on your domain/subdomain. That's expected behaviour.

 

[omexlu]

Then the problem is here to 1000%, because the 2 affected subdomains are both protected in the DocumentRoot by password, i will test that soon .

Anyway, thanks for your good help
