Hello,
After updating simple:press our wordpress multisite gave an error 500 and could only be viewed by disabling the simple:press plugin.
Also the simple:press plugin still needed to be upgraded (to be completed) so it was a bit of a catch 22 issue. Update caused error 500, can't update further cause of error 500 -> disable plugin = no 500 but can't update and can't use it then)
So after using the debug console a bit I found out that there was only 1 page causing a 500 error for the installation. When looking into the HTTP error logs I found:
[Tue May 10 09:50:29 2016] [error] [client MyClient] PHP Fatal error: Can't use function return value in write context in /var/www/html/BLABLA/wp-content/sp-resources/forum-plugins/mycred/sp-mycred-plugin.php on line 83, referer: http://BLABLA.com/BLABLA/wp-admin/admin.php?page=simple-press%2Fsp-startup%2Fsp-load-install.php
To avoid this error + the catch 22 I commented out the if around line 83 in sp-mycred-plugin.php.
After that I could run the update, and bring everything back to normal.

My apologies for you getting the error... but I am somewhat puzzled as I don't quite see what is likely to be wrong there!
Line 83 itself -
if (defined('myCRED_VERSION') && !empty(get_option('mycred_setup_completed'))) {has not changed. So if it causes an error condition it should always have done so. Line 84 changed to include the call to the WP function admin_url() but that should be fine as, if the function determines the site is an MS install it copes with this.
I will do some digging...

Thanks. That explains it - although doesn't explain why you have not had the error before as that code has been in place a long time.
It is the use of the 'empty' function. Prior to PHP 5.5 you had to pass an actual variable into the empty function. Post 5.5 it can take a function or expression that evaluates to a value.
I have also misinterpreted the WordPress minimum requirements for PHP. I see that it recommends 5.6 as a minimum version - not actually requires it. For the record the site states:
Note: If you are in a legacy environment where you only have older PHP or MySQL versions, WordPress also works with PHP 5.2.4+ and MySQL 5.0+, but these versions have reached official End Of Life and as such may expose your site to security vulnerabilities
So something, perhaps, for you to consider. But meanwhile I will correct the error and again - apologies for it happening. I would love to know why this has not reared it's head for you before but I guess that will remain a mystery!
