How to remediate 'dns error server cannot be found'

Hello,

When I browse to my site at www.richel.org, two things happen:
1. a screen flashes by which shows my site in a sort of locked maintenance mode (this is not how I left it)
2 a screen that says 'dns error server cannot be found'

Now by going into the mysql database I could possibly do something about nr 1, but how to get rid of this dns error?

Many thanks

Your error is with MYSQL not allowing any connections.

"The mysqli error was: Too many connections."

I would start with increasing your connections or reseting your MYSQL to see if it resolves the issues.

Thank you. You are partly right imho. I read somewhere onbthe net that part of my problem was caused by the PFDCreator toolbar en removing that indeed removed the dnserror page. Now I get a page telling me:
Site off-line
The site is currently not available due to technical problems. Please try again later. Thank you for your understanding.
If you are the maintainer of this site, please check your database settings in the settings.php file and ensure that your hosting provider's database server is running. For more help, see the handbook, or contact your hosting provider.
The mysqli error was: Too many connections.

.... which confirms your suspiocion.
I am on a shard hosting and I wouldnt know how to increase my connetcions, and by the way, this is a site that only me and my family ever visit.
I'll ask my host for a reset.
Thanks so far.

Hi there,

As expected. If you are a hosted site, then you have hit a hardlimit set by your host.  I would give them a call to have their host admins correct the mysql settings.

If you have PHPmyAdmin installed, you can see how many connections you are allowed in phpmyadmin's start page, in the "variables" link.

Wish there was another way.

Cheers,
