1. Bloated Database in WordPress Site’s Database
The more plugins you install, the more data needs to be stored in your WordPress site’s database.
Since your database and your server has a strict limit to how much storage space it has, the more information you collect in your database, the bigger it gets until it’s full-up and bloated.
This is particularly an issue because this causes your database to run inefficiently, which leads to a super sluggish site.
Activated plugins are especially a problem, but deactivated plugins still store data in your database and cause bloat. Even plugins you deleted can still store stray data.
2. Increase in HTTP Request ( Impacts on Site Loading Speed )
Many plugins offer a lot of functionality for the front end of your site. For example, allowing a visitor to book an appointment or browse and purchase physical or digital products.
Each time an HTTP request is sent, it uses up your server’s resources. The more that are sent, the more resources are used. If all your server’s resources are used up, your server (and site!) crashes.
That’s definitely not what you want since your visitors can’t view anything until you’re able to get things back up and running.
The other issue here is that each request takes time to process. The more HTTP requests you have, the more time it takes to complete and that translates into a slower loading time for your site.
HTTP requests are similar to your brain’s processing power. When you have to solve one little problem, it’s easy enough, but if you need to solve hundreds of little problems, it’s completely overwhelming. You get too tired and sluggish to problem solve.
Worst case scenario, your brain shouts “That’s enough!” and doesn’t accept any more problems, no matter how tiny.
3. Compatibility Issues
The more plugins you install, the higher your chances become of running into a compatibility issue. That’s when the code in two or more plugins don’t work well together and cause each other to break.
It’s like gears in a machine. When they’re compatible, the teeth of two gears line up and are able to rotate in unison. However, if those teeth aren’t lined up properly, the gears grind together and struggle until it spells destruction for both the gears and the entire machine.
Since plugins aren’t all written by the same developers, it’s difficult to make sure that every single plugin out there works well with each other.
Don’t forget: there’s over 50,000 plugins in the WordPress repository alone. It’s practically impossible to test one plugin against all the others out there to fix any compatibility issues.
5. Poorly Coded Plugins Can Create Troubles for your Site
As much as we may want to be, pobody’s nerfect—er, I mean nobody’s perfect—and mistakes do happen. Plugins are no exception.
No matter how skilled of a developer you are, statistically speaking, the chances of being able to write perfect code with no bugs is zero probability.
Every plugin is going to have its fair share of bugs, but there are also many plugins out there that are incredibly poorly coded. These plugins wreak havoc on your site in often multiple ways as mentioned above.
It’s like building a dam with plaster and a wood frame. At that point, you’re asking for the dam to collapse and flood the neighbouring city.
When you use a poorly-coded plugin, running into an issue is practically guaranteed.
How to Fix this Issue ?
Reduce the number of plugins you use – Using fewer plugins decreases the chance of running into issues.
Install multifunctional plugins – Try to reduce the number of plugins you use by installing plugins that include more than one feature that you need.
Decide what you really need and delete the rest – Review the plugins you have installed and the ones you have deactivated. If you haven’t used them in a long time or you don’t plan on using them at all, then delete them.
Review the plugin’s code – Check the code of each plugin you use to make sure it’s as clean and lightweight as possible. If you can’t do this, take the time to research the plugins you want. Check out reviews and only download plugins from reputable developers and companies.
- Clean up your database – Regularly do some spring cleaning on your database to get rid of as much bloat as possible.
- Use solid website hosting – Not all website hosts are created equal. Do your research and pick a host for your WordPress site that’s reliable and can help your site runs as fast as possible.
- Choose an appropriate hosting plan – Like choosing a website host, do your due diligence and pick a hosting plan that’s perfect for your site’s needs.
- Test plugins before you install them – Test plugins on a staging site or a local environment thoroughly before installing them on a live site. This gives you a chance to catch problems before it reaches your live site.
- Back up your site, often – Backing up your site regularly ensures you don’t lose everything in case you run into one of the problems mentioned earlier. If you do, you can restore your site to an earlier state.
- Install a security plugin – Using a security plugin can help catch and isolate issues before they break your site. That way, you can fix the problem or delete the plugin so it doesn’t do any (further) damage.
- Use plugins that are regularly updated and maintained – This decreases the chances of coming across problemed plugins that aren’t going to see bug fixes and performance improvements.
