Cannot enable cache after installing plugin

Hi!

Thanks for a good plugin i use it on many sites with good results.

However on one host I cannot enable the cache. On this host I get an error that the plugin was broken but now fixed.

Which it wasn’t.

After defining WPCACHEHOME manually in wp-config.php the error message goes away:
define(‘WPCACHEHOME’, ‘/path/to/super-cache’);

When i then try to enable the cache again i get no errors. But if i reload the settings page the cache has been turned off again.

I can see that the plugin generates a lot of files in the wp-content folder with different number series as names, for example: 16565600.php 73838132.php and so on. These files are a copy of the wp-cache-config.php file.

I’m not sure where to start troubleshoot this problem. The error log does not contain any entries after setting the correct WPCACHEHOME.
