Fatal Error when accessing Civi in WP Install
Unfortunately, the log message suggests you've hit a limit of your hosting provider.


  User snachodo_657 already has more than 'max_user_connections'


This could have various causes. If your hosting plan only allows a certain number of DB connections simultaneously and your site creates more than that, you'd see this.

I don't think it's a common issue for CiviCRM so it may be that the hosting provider has a low number of permitted DB connections, OR that your site is busier than most sites on your hosting provider.

It's worth noting that CiviCRM's DB connection methodology does not re-use Wordpress's DB connection, so for any visitor on a CiviCRM page, your site will consume two DB connections at once.

In the first case, I'd contact your hosting provider and enquire about the limit. It might be a config tweak they can make, or they may offer you a plan with more DB connections.

If that doesn't work out, you could ask an expert to investigate why your site is making too many connections, or look into hosting providers who provide support for CiviCRM sites.

Hope that's some help!
