Ok knownhost is suggesting that I should enable suPHP which means no XCache and to install memcache instead of XCache. Anyone have this set up on their server? How does it compare to running DSO and XCache?

memcached based vboptimise works fine http://vbtechsupport.com/1526/ / http://www.dragonbyte-tech.com/blogs...ache-hits-261/ :)

although you will loose more performance switching to suPHP than you'd gain from using vB optimise + memcached

but having vb optimise + memcached + suPHP is better than nothing.

I don't see the point of using suPHP anyways, so I will probably just stick with vb optimise and xcache :D

Chadi you ever find out what caused this? I'm getting the same error after saving settings.

I completely uninstalled 2.0.1 and deleted the files, then installed 2.5 btw. Forgot to add that I run vB 4.1.12 pl 2

From the looks of it, the host needs to set the var cache size. The xcache.var_count should be the number of cores directly and readily available to serve your website. If you need further assistance let me know. You can contact me via PM. Are you using VPS or shared?

Make sure you flush the vboptimise cache.

Why are you using 2.1 or 2.5? I'm using 1.3...

Yep they did not enable the var cache, and I'm using 2.5 because I'm thinking of upgrading to vB 4.2.

Apologies, I thought you were meant 2.5 xCache version as opposed to vBOptimise.

Ok so I haven't noticed any change and when I click on the "Resource Statistics" link the page shows no savings. I have attached screen shots of my settings, I didn't install xcache ... my host did so perhaps there is something else they need to tweak?

Question ... do I have to uncomment the relevant lines in config.php?

Go to /includes/ and open config.php you need to uncomment:
and set it to
Then, you need to go to /includes/datastore/ and open the datastore.php file and set all the vars (between each '') to e.g. If you need further assistance feel free to contact me.
