I've got a webserver installed with Apache and PHP with mod-security. The problem is that mod-security seems to be incompatible with the PHP installation.
I get the following result in the apache error log when I restart apache:
[Mon May 07 09:28:45.000596 2018] [:notice] [pid 61272] ModSecurity for Apache/2.9.1 (http://www.modsecurity.org/) configured.

As you can see, the error talks about the PCRE version being incompatible with the loaded version. I can't find any information about what this means or how I can fix it. Does anyone has a clue about what to do?
