Too Many Connections Error in OpenCart

Posted by Will on August 5, 2025

If your OpenCart store suddenly shows an error like “Too many connections” or "Max user connections", this means your site has hit its server limit and can no longer talk to the database.

You might be experiencing other issues alongside this - such as slow loading times, a laggy admin panel, random 500 errors, or checkout failures. All of these are signs that your server is under pressure and struggling to keep up.

Why Does This Happen?

Every time someone visits your website, OpenCart connects to your database in order to load things like products, categories, pages, customer information and more – however, your server can only handle a certain number of these connections at one time.

If your site gets too busy, the server will hit its maximum connection limit, and any new requests will be blocked – bringing your store to a halt. This kind of downtime is more than just frustrating, as it can directly impact your sales, and your business reputation!

If you’re using cheap or shared hosting, the number of database connections allowed is usually very limited. While this can be fine for a basic blog, for any website experiencing a higher number of traffic it will always be a bottleneck. If this is the case - it is probably time for an upgrade.

What Can You Do?

There are some things you can try to help stop this error from showing up. However, these are only temporary fixes, especially if you want your website to increase in traffic:

  • Disable any heavy or non-essential extensions
  • Make sure caching is properly installed
  • Check server logs for unusual spikes in traffic - these could be caused by bots
  • Limit bots and scrapers with a firewall
  • Have a technical audit to find and remove anything that's bloating the website

The Real, Long Term Solution

The truth is - none of this will matter if your current hosting can't handle the traffic you are currently getting. If your website is growing, you will need your hosting to grow with it. To avoid getting these types of issues long-term, you will need a hosting environment that's built to handle the traffic you're getting.
