PDFlib problem: Unable to initialize module

Nextcloud version: 13.0.5
Operating system and version: ? (it’s hosted with a webhoster)
Apache or nginx version: ? (it’s hosted with a webhoster
PHP version: 7.2

The issue you are facing:
When I go to ‘logging’ in the settings, there is an error shown every second:

Error	PHP	PHP Startup: PDFlib: Unable to initialize module Module compiled with module API=20160303 PHP compiled with module API=20170718 These options need to match at Unknown#0	

What should I do?

I think I might have set up the nextcloud with a lower version of php initially and later activated pühp 7.2 in the admin panel of my webhoster.
