Any suggestions ?

I just upgraded to 4.1.19 this past week and found out that I am getting a 500 error as well when my users attempt to access the home page index.html in the public_html folder. Seems the index.php takes over and gives a 500 error or just a white blank screen.

However, if they type in the full url to the forum it will pull up fine.

 

I also upgrade up to PHP 7 which apparently might be the issue:

PHP Fatal error: Uncaught Error: Call to undefined function set_magic_quotes_runtime() in /home/XXXXX/public_html/XXXX/initdata.php:382
Stack trace:
#0 /home/XXXXX/public_html/index.php(50): require_once()
#1 {main}
thrown in /home/XXX/public_html/XXX/initdata.php on line 382

I am wondering if I need to downgrade PHP back and if 4.1.19 will run without PHP7 ?

Better for you to open a ticket with ips. 

I have. They told me it's not a forum software issue but a PHP one. Thought maybe somewhere here ran into this.

You really have to check and/or post the errorlogs of your webserver and php.  I ran ips 4.1 (also 4.1.19.1) with php 7.1 for a long time without an issue on 7 installations 

initdata.php?

This file does not come with IPS 4.1.19, just init.php

Check your custom index.html page to see why it is including initdata.php instead of init.php

I'll go check the index.html later when I get home. It's a simple html opening page and shouldn't have any calls to a php file but I'll go look.

Thx for the responses.
