WampServer

I am using Wamp64 version 3.1.4 and had ssl working fine with apache 2.4.34.

I also updated the VC2017 (32bit and 64bit).

I updated php to 7.2.12, mysql to 5.7.24, and apache to 2.4.37.

I then enabled the ssl mod for apache in the httpd.conf and made sure the httpd_ssl.conf had the correct paths to the certificates.

Unfortunately apache fails to load and generates no error log. When I manually try to run httpd.exe in a command prompt I get the below error:

httpd: Syntax error on line 185 of C:/wamp64/bin/apache/apache2.4.37/conf/httpd.conf: Cannot load modules/mod_ssl.so into server: The specified procedure could not be found.

Any help would be greatly appreciated.

Sounds like you forgot activate one of the other required modules, probably one of the socache modules

From the top of the httpd-ssl.conf file

# Required modules: mod_log_config, mod_setenvif, mod_ssl,
#          socache_shmcb_module (for default value of SSLSessionCache)

Also remember that the httpd-ssl.conf file is not copied forward to the new Apache from the old Apache. This you have to do yourself, while remembering to make sure you check that nothing in this area has changed between versions of Apache.

I don't think that a missing module is causing the issue.
