Teething Issues Upgrading to PHP 7.2 for Xenforo2

[Chris Radford]

Hi all,

We are trying to upgrade to PHP 7.2 however when we do, the following errors occur and website ceases to display;

Fatal error: Uncaught Error: Call to undefined function mysqli_init() in /home/onefootb/public_html/src/XF/Db/Mysqli/Adapter.php:152 Stack trace: #0 /home/onefootb/public_html/src/XF/Db/Mysqli/Adapter.php(28): XF\Db\Mysqli\Adapter->makeConnection(Array) #1 /home/onefootb/public_html/src/XF/Error.php(85): XF\Db\Mysqli\Adapter->getConnection() #2 /home/onefootb/public_html/src/XF/App.php(1902): XF\Error->logException(Object(Error), true, '') #3 /home/onefootb/public_html/src/XF.php(145): XF\App->logException(Object(Error), true) #4 [internal function]: XF::handleException(Object(Error)) #5 {main} thrown in /home/onefootb/public_html/src/XF/Db/Mysqli/Adapter.php on line 152

Can anyone shed some light on what these errors mean?

Thank you.

Didn't enable mysqli was for php 7.0 , schoolboy error! Fixed now.

Website now appears to be operating largely OK- however, on thread view page loads we are hit with this;

XF 2.0 requirements
The requirements for running XF 2.0 have changed since XF 1.5. The recommended requirements are as follows:

• PHP: 5.4.0+
• MySQL: 5.5+
• PHP extensions: MySQLi, GD (with JPEG support), PCRE, SPL, SimpleXML, DOM, JSON, iconv, ctype, cURL

----

You need iconv i think.
