You may encounter numerous frequent mistakes when managing a WordPress website, however, this is one of the rarest. Only a few individuals are aware of it. It's because it has something to do with the maximum amount of database calls a website can make when it's hosted on a shared server.

As you may be aware, shared hosting is used by the majority of personal blogs and small company websites, and such servers have restricted capacity. A QUERY packet error indicates that the server is not ready to submit any further database requests. It implies that your website will remain unchanged.

This error will appear whenever you change a blog article, publish it, install a plugin, or install a theme. It indicates that everything linked to the database will come to a halt.

We'll tell you about the probable reasons and solutions in this post.

Start by optimizing your database:

It has to do with the number of database requests, as we indicated earlier. And you should be aware that each web hosting service has its own set of restrictions. Some organizations compute the limit in terms of total database queries per hour, while others do it in terms of total database requests per day.

In any instance, if the number of requests exceeds the limit, no more requests are handled, and you receive an error message. The worst part is that it may cause your website's design to be disrupted. It may be beneficial if you can optimize the database.

Note: Most users don't think about keeping their databases optimized, and as a result, they have a lot of issues.

It's always a good idea to install and utilize a database optimization plugin now and then. To maintain the database as compact as possible, you may utilize WP-Sweep, which is one of the lightest and most effective WordPress plugins.

You should be aware that every time you edit, update, or publish an article, or when you install a plugin, theme, or something similar, a new database table is created in the database.

It indicates that the database's size has grown. There are a few things you should do.

● Delete the database tables in the drafting state.

● Delete the posts that have been removed from the database.

● Revisions should be removed.

● Spam comments should be removed.

● Meta: Remove duplicate comments

● Delete duplicate post meta information.

● There are several more alternatives available to you.

Activate a CDN:

As you may be aware, a CDN may assist you in improving website speed by producing a static version of your website so that a returning visitor does not have to utilize all of your website's resources again, and the CDN displays the website. A CDN, of course, works as a firewall between your website's server and the user's browser, therefore it's a nice thing to have.

It could be able to assist you to minimise the number of queries your website is now making. HTTP requests are performed when a user inputs your website's URL and accesses it, and a CDN handles them properly. On the other hand, if you don't have it, the web hosting server may feel a load because it may not be capable of managing such a large number of requests.

You'll get an error at that point. A CDN may be able to assist you in resolving this issue. If that is not the case, there is just one option.

Make the switch to managed or cloud hosting:

The shared web hosting has limited resources, and as your website grows in size, it demands more resources and makes more database calls, necessitating more resources and database requests.

A better server is necessary to handle such requests. You may upgrade to managed hosting, which is less expensive than Cloud hosting. However, it is dependent on the firm you select. Many Managed Hosting providers, but not all, provide great services at a fair price.

You may now be considering switching to another shared hosting provider. You should, but don't move your website without first gathering the necessary information. You must know the total amount of database requests per hour that your current web hosting enables your website to perform.

Consider the case when your website receives 8,00,000 database requests per hour. It may be too much for a shared web hosting account to handle. Even for their most expensive hosting package.

As a result, only managed or cloud hosting is an option.

If you try these suggestions, your problem will be solved:

The database optimization worked for me since I had a database that was 200MB in size but only needed to be 44MB. It's possible that this is also the case for you. You could try deleting the utilized database tables, tables produced by removed posts, superfluous information, and so on if you haven't already.

In general, a CDN may be quite beneficial. Even if you don't anticipate any issues, a CDN should be enabled on your website. Who doesn't want their website to load quickly? Well, you should consider it. You may either use the free Cloudflare CDN or pay for a premium CDN such as MaxCDN.

The major objective is to reduce the number of database queries made by the website. Try deactivating or removing the plugins you don't require. A plugin may occasionally run out of memory, causing everything to come to a halt. The main objective is to optimize the database such that an error does not occur.

If your website grows, you should constantly search for a better web hosting provider that can manage a sufficient number of database requests.

We hope you'll be able to pull it off. If you have any further questions, please leave a remark.
