Incorrect database access credentials

However, visitors may not see this error on the frontend right away. This is because your site will most likely continue to serve from cache until it expires. For example, at Kinsta, all WordPress sites are cached for one hour by default. Therefore, if a site continues to serve from cache, it may appear acceptable to a visitor.

At Kinsta, our support team can increase your cache duration to, say, an hour or even a week if you wish. If you have a site that doesn’t change very often, this can increase your site’s performance as it doesn’t need to fetch new files as often after the cache expires. And in cases like the above, the frontend of the site in most cases (unless you have a script or part of your site that breaks the cache) would stick around for much longer.

When visitors try to access your site while this error is occurring, an HTTP 500 status code will be generated in your logs. This same status code appears with an “internal server error.” It means that something has gone wrong on the server, and the requested resource has not been delivered. When everything is working properly, your site will generate an HTTP 200 status code , meaning that everything is fine.

Kinsta clients can review their site's logs in the MyKinsta dashboard:
