funny letters and white screen

Hard to say. I assume when u say you disabled it you are saying you did so via the admin page > Plugins area. Can u “Remove” the plugin too.

1. In your wp-config.php is the define('WP_CACHE', true); line gone?
2. Under wp-content do you still see: advanced-cache.php ?
3. In your htaccess file is there anything that says W3TC ?
4. What caching method did you select originally — Disk Enhanced, Disk Basic? something else?

OK thanks for the pointers…
I have emptied all the caches – disabled the plugin – deleted the plugin files including the cache folder (well remained it) wp-content/cache and wp-content/w3tc-config

taken out the (‘WP_CACHE’, true); line in the wp-config.php file and taken out all references in the .htaccess but still no joy ….

So after disabling and deleting the plugin from within WordPress admin page you still had to manually remove the info/files from your htaccess + wp-config + w3tc-config + cache ? That’s strange…normally when you have wp deactive the plugin it takes strips its content in wp-config and htaccess..and when you remove the plugin it deletes teh cache and the wt3c-config dir along with its /wp-content/advanced-cache.php (and object-cache.php) file.

Btw, what is “PleskLin”? … i noticed a X-Powered-By: PleskLin in your page headers.

@detoner,
Have you tried changing your theme to a default one? Does the error persist when you do so?
I’m inclined to think this is not strictly w3tc-related, seems like some faulty gzip configuration to me. Could you post the content of your .htaccess file too?

@kimberly, this is off-topic, but I’d love to hear your thoughts on these two issues #31 and #32

Go to your htaccess file and remove all the W3TC lines this looks like a gzip error. This looks like what happens when you GZIP the content twice.

I have only uploaded now the basic re-write content in the .htaccess file

changed the theme to twenty ten but no joy..

Tried to restore an older database before this happened and still I am getting the funny characters…..????
