[Forum] Fatal error: Storing of variables is not enabled within XCache in [path]/includes/class_datastore.php

[RobAC]

I just moved my site/forums to a new server which is running php 5.4. xcache is installed on the server, however, I cannot get the forums to load and get the following error:

Fatal error: Storing of variables is not enabled within XCache in [path]/includes/class_datastore.php

What does this mean and how can I fix this?

What's your Vbulletin version?

[RobAC]

4.2.1

You will need to upgrade to 4.2.2 (or downgrade to PHP 5.3) as PHP 5.4 is not suported for 4.2.1. Not 100% sure it would cause a fatal error but you need to sort that first.

besides ideally using vB 4.2.2 latest for PHP 5.4, the error you have is most likely misconfigured Xcache settings for data caching you have disabled Xcache variable cache - i.e. if you set xcache.var_size=0 in Xcache settings as opposed to enabling it with an actual value to allocate memory to the variable cache i.e. xcache.var_size=32M and restarting apache or php service for changes to take effect

The error has nothing to do with php (or vb) version.
As George rightly points out, it means xcache is not configured correctly.

I did say that the error probably has nothing to do with the PHP version but it is never the less something that needs rectifying.
