Proxy settings can currently not be determined load error 500

[maffy]

Running home server with Apache 2.4
After upgrade Apache 2.2 to 2.4 an PHP 7, SMF fora are not loading at all.


Installed 2x SMF forums ver 2 months ago, and they are running fine, until i upgrade win7 to windows 10 and find that apache 2.2 has to be upgraded aswell.
Installing Apache Version   Apache/2.4.20 (Win32) mod_h264_streaming/2.2.7 PHP/7.0.6
SQL server is the same and runs fine also.
The server is not to be running any proxy.
Problem proxy detection is temporarily not determined http error 500 in browser. All ohter domains and pages with PHP and SQL are fine.
Something happened with the way the new Apache server is doing this.
A new premade setting in httpd.conf is
# Configure mod_proxy_html to understand HTML4/XHTML1
<IfModule proxy_html_module>
Include conf/extra/proxy-html.conf
</IfModule>

paranormal.mcraft.dk main site working ok
paranormal.mcraft.dk/forum forum error
lthy.dk forum error

Any idea what to change?

[LiroyvH]

Don't quite follow. Exactly what is the error you get on the screen; and what shows up in your Apache HTTPD "error_log" file?

[maffy]

The link http://paranormal.mcraft.dk/forum shows the error.
I get this in danish:
paranormal.mcraft.dk kan i øjeblikket ikke behandle denne anmodning.
HTTP ERROR 500

Starting error finding tells that proxy settings cannot be determined automaticly.

Do you have a proxy configured on your computer or the router...?
It just shows a blank page here (no 500 error) and those errors in the error_log are unrelated.

The blank page has been shown to people with mobile devices.
I get a little more as i typed here, when from a PC.
I also tell, that i dont want to run proxy. i really don't think i have proxy, but windows 10 starts with IIS which i had
to exterminate and uninstall to get the port 10 free again.

Starting at the main page same domain http://paranormal.mcraft.dk there is the wanted page shown fine.

[LiroyvH]

I'm not on a cell phone. On other browsers I can get a problematic response, but I'm not sure what you mean about the proxy...?

Unfortunately, without any meaningful errors its a bit hard to troubleshoot what problem you may have.
I do recall there might be some issues with SMF + PHP7, but someone from support/dev will probably know that better than me if there indeed are issues.

[maffy]

When i configured PHP.ini, i recall, that there was no MySQL but an MySQLI section. Perhaps i am running MySQLI instead, which is much smaller requirements for PHP

These are the response headers I get from visiting http://paranormal.mcraft.dk/forum/:

Could the error be caused by PHP 7?

Edit: The topic @CoreISP linked indeed confirms that this issue is caused by PHP 7.

[maffy]

Its possible this PHP 7 version does not run MySQL but only MySQLI?

[LiroyvH]

Yes, check the topic and the linked mod for a fix

[maffy]

The suggestion points at changing the settings to expect mysqli instead of mysql.
Changing this
$db_type = mysql';
and reloading cache has no effect here.

[LiroyvH]

Those are instructions for *after* you have installed that mod.

[maffy]

Thank you all. Installed the mod and it works.

[LiroyvH]

Great to hear that! Enjoy

[maffy]

Thanks.
New problem showed up. I forgot admins password (or it is not working).
When providing user nick name for email option, i get:
An Error Has Occurred!
Your session timed out while posting. Please go back and try again.
People can not register either http://paranormal.mcraft.dk/forum

I see more of this kind of posting but none with this issue of password after migrating to mysqli.
