[Forum] 4.2.3 to 4.2.4 - PHP5.4 to PHP 5.6 - white screen when enabling opcode cacher

[glennybee]

Hi all,

I've recently updated from PHP5.4 (running vb4.2.3) to PHP5.6.30 via EasyApache 4 on WHM. As soon I restarted Apache, I got a white screen and the forum wouldn't load. I was running XCache so I disabled this in config.php and now the forum loads ok. My host told me that Xcache is not supported in PHP5.6 so I disabled it in php.ini.

Now I've tried to install APCu and as soon as I enable this in config.php I get the white screen again.

If I enable Filecache then it appears to work and the site loads ok.

Hoping someone can assist with this issue. Much appreciated.

OK so after some more searching it seems that Zend Opcache is enabled by default in PHP 5.5 and above...which it is. So do I really need another opcode cache mechanism?

Your host lied to you, xcache supports php 5.6 just fine, Ive been using it (v 3.2.0) for over a year.

Hello,

Both XCache and Zend OPCache do basically the same thing.

You can use either one not both because you'll get fatal errors like "cannot redeclare class *****" that renders your forum unable to load.

I recommend you to stick with Zend OPCache.

Kind regards,
George.
