Error installing Dovecot, now 502 Bad Gateway on server

[Shawn1]

Hello,

I tried to install Dovecot on my server and move away from Courier IMAP... But when I try to install in Plesk Installer I get the following errors... What are my options? :-\

Now I also cannot go to view my home in my control panel... I get...
502 Bad Gateway
nginx

My websites still work. I have not tested my email.

Help please?

I am running CentOS 6.5... and Plesk 12 but not sure of exact version of Plesk 12.

I had to upload file because error is over 10,000 chars.

I restarted server via SSH and the 502 Bad Gateway issue has been resolved.

I can also send email outbound... but now emails are not delivered Nor do I receive a bounce back. I will wait a bit maybe server is overloaded restarting.

Email working again after going back to Courier IMAP... Send/receive OK...

I believe I have a PHP issue relating to tables... I believe my server host 1and1 tried to update PHP many months ago but never finished upgrade and tables need upgrading/repair?

Consider to re-run bootstrapper repair, after you solved your issue, please.
