If XCache has authentification setup (in php.ini, or xcache.ini depending on setup), then you need to configure the XCache username/password within vboptimise/config.php (in plain-text), and turn on XCache Authentification within the vB Optimise settings :)

None of that is required however if your xcache installation has authentification turned off.

Hello, I get blank screen when you go to: vboptimise.php?do=flush

that may be? use vbulletin 4.0.3

No problems with 4.0.3 here.

Run a system test.

I'm having the same issue. :(

@softvnzla & smnoel

Please run the System Test within the Admin CP (under vB Optimise) and let me know which tests succeed or fail. Generally if flush cache is failing and you're running XCache you'll need to enable XCache configuration within vBO options and also edit ./vboptimise/config.php to specify your XCache username/password (or alternatively disable XCache admin authentification within php.ini).

If it's eAccelerator, you'll need to provide the script access to run the flush command, more information: http://eaccelerator.net/wiki/Setting...0.9.5andhigher

Any member see improvment after upgrade to full.

I can't comment, but here's a quote from someone who has Pro: https://vborg.vbsupport.ru/showpost....&postcount=130 :)

Installed and started to get database errors. And finally crashed.

Do you have any examples of the DB errors so we can try to diagnose what the issue was? :)

Thanks,

Iain

Database errors? No one else has encountered that issue. As Iain said above if you could provide what error that was it would be great. Not sure how DB errors caused you to crash either.
