4.2.5 Database error and PHP question

[Flipfloptrader]

Hi all,

I have upgraded from 4.2.4 to 4.2.5 and it seems to be working but get this database error whenever I log into the admincp:

Use of undefined constant SAPI_NAME - assumed 'SAPI_NAME'
/home/flipflop/public_html/includes/class_core.php on line 6153

MySQL Error :
Error Number :

#2 vbulletin_exception_handler() called in on line

Also, I have the ability to change to PHP 7.1 but when I try and select it it causes the forum to break and just displays this:

Call to undefined function split() on line 4 in /home/flipflop/public_html/forum.php(791) : eval()'d code
#0 /home/flipflop/public_html/forum.php(791): eval()
#1 {main}


Hopefully that makes sense to someone, haha!

Fixed the error for registration as it was a plugin error.

Resolved with some more googling and researching. It was a username colourbar mod effecting it.

Glad you resolved it. Seems they weren't defining things properly. So the PHP notice caused a cascading effect.

Going to bump this due to another site that recently had this same problem. On the second site, the issue was due to the MySQLi library not being available in PHP within the AdminCP due to an extraneous php.ini file. It seems we define the SAPI_NAME constant after trying to connect to the database and since it isn't defined, that overrides the database error.

1. Make sure that MySQLi is available in PHP.
2. Make sure there are no extraneous php.ini files in your directories.
