Roundcube plugins "Soap Error: Internal Server Error"

I was following this guide for setting up roundcube plugins, mainly because i can't explain anymore to people how to reset their passwords through CP, it would be much easier just through roundcube. https://www.howtoforge.com/tutorial/ispconfig-3-roundcube-plugins-on-debian-stretch/

But i am getting the error "Soap Error: Internal Server Error" when i try to change any settings through roundcube. I did a bit of research and google, there was suggestion soap is not installed. So i checked and since i have php7.0 to php7.4 versions installed on server, all of them have soap installed. The version in use when i type "php -v" is php7.4.6 cli. php7.4-soap is already installed.

In Roundcube logs i didn't find anything except this

Code:

PHP Warning:  count(): Parameter must be an array or an object that implements Countable in /usr/share/roundcube/program/lib/Roundcube/rcube_plugin_api.php on line 438

However in apache logs i found this

Code:

You do not mention what Operating System is on that host.
Are you sure the default version of PHP for the installed OS has not been changed?

 

Debian 9. ISPConfig 3.1.15p3, Roundcube 1.2.3. It say php7.4 when i type "php -v" in terminal. I guess that is default running php version.

 

That is indeed the default PHP version now. But for Debian 9 it should be 7.0. How have you installed the additional PHP versions?
https://www.howtoforge.com/tutorial...bian-default-php-back-to-the-original-version

 

The 7.0 version was indeed default at the time of installation and setup of the server. The ISPConfig use 7.0 as default, but yesterday i did an update to the server "apt-get upgrade" and it installed the latest packages of everything that was needed to update and with that update, the 7.4 version has been installed and switched to as default it seems. (just a note i didn't have Roundcube plugins setup before this so i don't know if would work before, i set them after the update)

I take a look at the guide and it seems quite good, is this the only command for php version change ?

Code:

update-alternatives --config php
update-alternatives --config php-cgi

I tried it, the "php -v" returns 7.0 version now, but it's still the same, i have the same error in Roundcube. On the other guide i found different commands, is there a difference ?

Code:

sudo update-alternatives --set php /usr/bin/php5.6
sudo update-alternatives --set phar /usr/bin/phar5.6
sudo update-alternatives --set phar.phar /usr/bin/phar.phar5.6
sudo update-alternatives --set phpize /usr/bin/phpize5.6
sudo update-alternatives --set php-config /usr/bin/php-config5.6

 

Update, something went wrong somewhere with php or quite possibly when i did an update.

But anyway i got it working now by reinstalling php7.0.

So i did "apt-get remove php7.0*" and then "apt-get install php7.0*" and now Roundcube plugins works.

I don't know if this is somehow related but php version removed and newly installed are different.
Removed php was PHP 7.0.33-29+0~20200514.36+debian9~1.gbp126f6f
Newly installed is PHP 7.0.33-0+deb9u7

Also i had to enable Remote Access in ISPConfig
