So... after being hacked and hacked and hacked again, I have changed my passwords to an unbelievable combination and think i have finally stopped the swine who persists.. but now... I've gone to install another plugin and then BAM - all current plugins have this message...
The Plugin has been deactivated due to an error: The plugin does not have a valid header.
All plugins are still in the plugin directory, but not available to work with on WP... The only way is to remove them form the file (from cpanel) and re-install.
Is there an easier option... I have a few sites i need to fix... :-(
Thanks.
