Compiled static into https-2.4.46 and it broke PHP in many locations

[4nanook]

I have an Apache server 2.4.46 which all modules are compiled in static. When I added this one it broke php, php would only execute in some places afterwards. In other locations it would print the PHP code instead of executing it. I was not able to discern a pattern and this involved NO change to the Apache configuration, ,just added this to the configuration file._

[4nanook]

I can't see how to select or I would add the working and non-working configuration.

What sort of environment are you working with? Please provide the following information:

1. OS Kernel (MAC/WINDOWS/LINUX/BSD UNIX/etc)
2. Distribution source & version number (e.g. CentOS 7, Ubuntu 1804, Windows 10, MacOS Sierra, etc.)
3. Apache source - is this compiled from an unmodified distribution source package or is this a customized source fork of some kind?
4. Apache threading model (mpm module) used - event, worker, prefork, or something else?
5. PHP module - are you using mod_php or one of the CGI options?
6. Where did you get the source for mod_php and the standalone php package?
7. What compiler and version are you using? (GCC 7, MSVC 14, etc.)
8. Please provide a complete list of all modules that you have statically compiled into Apache
9. If possible, please attach your Apache configuration file(s). Feel free to mask any sensitive bits with ***** or something before you send them.

If you got it working, please let us know so that we can close this issue as resolved.
If the issue is not resolved, please provide the information we requested so that we can attempt to diagnose it.

No it is still broken, I grabbed the most recent code, see the two attached images. Without mod-auth-external compiled into Apache 2.4.46, owncloud displays properly, WITH mod-auth-external compiled in it just prints rather than executes the PHP code.

 Only change is the last line commented or uncommented.  If uncommented to include mod_authnz_external.c then it

breaks printing the PHP code for nextcloud rather than executing it, but Wordpress still works.

What sort of environment are you working with? Please provide the following information:

3. Apache source - is this compiled from an unmodified distribution
   source package or is this a customized source fork of some kind?

4. Apache threading model (mpm module) used - event, worker, prefork,
   or something else?

6. Where did you get the source for mod_suphp?

9. If possible, please attach your Apache configuration file(s). 
   Feel free to mask any sensitive bits with ***** or something before 
   you send them.

Please provide the information above so we can try to figure out what's going on. Also, please provide the following:

1. It looks like suPHP was discontinued a couple years ago. Are you using a fork? If so, which one?

2. Could you please attach your apache and php error logs from a single run? Feel free to mask any sensitive bits with ***** or something before you send them.

[4nanook]

The Apache source itself is unmodified. but I am using apr 1.6.5 rather than apr 1.7 because 1.7 and openssl 1.1.1g has a symbol mismatch and will not load. 1.7 works okay with 1.1.1f but not 1.1.1g.

Source for mod suphp came from here: https://github.com/lightsey/mod_suphp/
But is slightly modified. I've removed the check for parent directory permissions which did not work well with my setup, so it only cares about the owner of the php executable.

I've zip'd up a tar file of the conf attached. Why this won't accept plain tar or .xz is beyond me.

[bimimicah]

I noticed you have .htaccess directives turned on for nextcloud. Could you please attach those files? Alternately, feel free to send them directly to me.
As a side note, I noticed an old key database and some other things which may not have been intentionally uploaded, so I have removed the link and contacted GitHub support to request that the uploaded attachment be removed. I still have a copy of the zip on my side for reference as we troubleshoot this issue, which I plan to delete after closing the issue.

[4nanook]

Could you e-mail me the location (which file(s)) those old keys are in? There shouldn't have been any in the actual conf, I thought I had externalized all of them but obviously missed something.

Sorry I haven't had a chance to get back to this. I will try to carve out some time soon to try building a similar setup to test, but I don't know when that will be.
If you have any php or httpd log files to attach, that will be helpful as well.

[4nanook]

Thought it been a while so I tried compiling in the module again, broke the server in the same way, instead of php being interpreted, it just prints the code as if it were not php code.
