Php_soap.dll missing error

New installation of IP v1.5.9 via Softaculous on Plesk Linux VPS. For some operations, such as saving an invoice, the cog spins for a long time and then I get the ‘It seems that the application stuck because of an error.’ message. I set up debugging. The error that is listed there is:

ERROR - 2018-06-06 17:44:23 --> Severity: Core Warning --> PHP Startup: Unable to load dynamic library ‘/opt/plesk/php/7.1/lib64/php/modules/php_soap.dll’ - /opt/plesk/php/7.1/lib64/php/modules/php_soap.dll: cannot open shared object file: No such file or directory Unknown 0

Soap is installed on my server - confirmed. No, the file listed is not in that directory and indeed there are no dll files on the server at all, because it isn’t a Windows server. How do I stop this error?

(In fact the invoice is saved correctly, and this is an inconvenience of time and extra clicks.)

Thank you!


This rather sounds like a misconfiguration of Plesk which may better be solved in the Plesk support forums.
