I recently had four sites hacked simultaneously. Bluehost provided a backup restore which brought everything back. I made sure I had the latest version of WP, checked there were no updates to plugins, which I do daily, and changed my passwords using the cPanel generator. The following day the external sites were fine but the dashboards only contained a list on the left of hyperlinks that don't work.
I deleted the plugins through cPanel which has brought back two of the dashboards, but two remain messed up. I uploaded the wp-admin folder from a previous backup but this hasn't worked either.
I've scanned my machine which didn't throw up any bugs and I've checked the condition is the same in other browsers, which it is.
Any help/guidance would be appreciated.
