Hi, I have a vbulletin on my server and I had some problems with the site. After trying to backup the data, it didn;t work and after that I was forced to reboot the server to see if the problem would be solved. After the reboot I got below msg and my mysql and panel are not working. Sites are down.... I didn't do anything on the database and I only have a partial backup and the a whole backup. How can I solve this issue and how to prevent from happening in further. This is 2ns time this happend to me and I would like to prevent this or in any cause to solve this issue fast. Please advise and many thanks in advance. When I want to enter plesk on website.
