When I hit 'delete' on the plugins listing, then on the confirmation page 'Are you sure you wish to delete these files and data?' I hit 'Yes, delete these files and data'. This takes me to a blank page, view source shows nothing. I've got the following settings in php.ini:
error_reporting = E_ALL | E_STRICT
display_errors = On
log_errors = On
View source on the blank page shows nothing at all, and there's nothing in the log.
If you want any more info or for me to perform any debugging steps just let me know.
