I see you have busy days... assume it is due to the change of servers. My question is also related to this - at least I hope so!!! - I cannot login to my wp-site (admin) - error message is that the server is slow in response.... I guess this is due to the server change?
This is the message I get:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, firstname.lastname@example.org and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.
