Web Security & Maintenance

“Error establishing a database connection” means WordPress can’t reach the database that stores your content — usually caused by wrong credentials in wp-config.php, a database server that’s down or overloaded, or a corrupted database. A 500 Internal Server Error is a different, more general error — it’s sometimes caused by a database problem, but far more often it’s a PHP memory limit, a plugin conflict, or a broken .htaccess file. This post covers both, and how to tell which one you’re actually dealing with.

The only real way to know a WordPress backup works is to actually restore it — ideally to a staging site — and confirm the site loads, the database is intact, and nothing critical is missing. Checking that a backup file exists or that a plugin says “backup complete” tells you nothing about whether it can actually save you.

A standard WordPress maintenance retainer includes core, theme, and plugin updates (usually tested on staging first), daily offsite backups, uptime and security monitoring, malware scanning, periodic reporting, and a set amount of included developer time for small fixes. Higher tiers add performance optimization, a content updating SLA, faster response times, and dedicated support.

WordPress maintenance in 2026 typically costs $40–$80/month for a basic DIY or automated plan, $150–$300/month for a professionally managed care plan on a small business site, and $500–$2,000+/month for ecommerce or enterprise sites. Hourly rates for one-off work range from $30–$150/hour for freelancers and $100–$250/hour for agencies.
