What plugins are not allowed?

There are more than 54,000 plugins for WordPress out in the universe and most of them are going to work splendidly on Funnelcloud. However, there are a few categories of plugins that either duplicate functionality that Funnelcloud already provides, or are known performance-killers on sites. 

We believe that users shouldn’t have to “fiddle” with their site to get the best performance and security. As a managed WordPress host, our goal is to make sure you’re starting out with a site that already works really well.

 

Backup plugins

Funnelcloud already has you covered on the backup front. We back up every site each and every night on external servers.  We allow you to easily restore and download backups from the Funnelcloud dashboard.

Backup plugins, on the other hand, are incredibly resource-hungry. When running, they can take a big bite out of the resources you need to deliver content to your visitors and really slow your site down at inopportune times. For larger sites, some of the MySQL queries can even take your site offline. These plugins also often store large backup files on your server, which can unnecessarily fill up your disk space.

Examples of disallowed Backup plugins:

  • BackupBuddy
  • BackWPUp
  • BackUpWordPress 
  • Others

 

If you’d like to keep your own backups in additions to the ones Funnelcloud keeps, we recommend downloading a backup from the Funnelcloud dashboard.

Note: If you do want a regular backup in addition to Funnelcloud’s nightly backup, try choosing a plugin which allows you to store backups offsite like VaultPress. Your site’s performance will still take a hit while the process is running. In an attempt to keep data usage to a minimum, we’d advise you only allow the plugin to store of one day’s backup on the site itself.  

 

Caching plugins

Funnelcloud handles caching at the server level, eliminating the need for caching plugins. Server-side caching is significantly more efficient and scalable than any plugin-based caching, as it doesn’t rely on PHP at all. This aside, caching plugins run the risk of interfering with the caching we already have in place.

In addition, plugin-based caching solutions tend to cause serious issues when used in tandem with Funnelcloud features that move or duplicate sites, including Blueprints, cloning, and Staging.

Examples of disallowed Caching plugins:

  • W3 Total Cache
  • WP Super Cache
  • Batcache
  • Other

 

Note: Some caching plugins also handle other tasks, like JavaScript and CSS file minification and concatenation. W3 Total Cache is among these, as is WP Rocket. These are tasks which are ideally handled at the site development level, but if you would prefer to use a plugin, that’s fine. We just recommend not using the caching features of the plugins and leaving that to our servers instead.  Another fantastic option is to use CloudFlares CSS and minification tools.

 

 

Security plugins

Funnelcloud servers are configured specifically with WordPress security best practices, and we have server-level blocking and scanning for hackers and malware. We prevent brute force attacks, lock down core WordPress files, and take many other security measures for you.

Security plugins duplicate this, and in many cases significantly slow down sites by interfering with our caching, bloat the site’s database, and/or interfere with our native security software.

Examples of disallowed Security plugins:

  • Wordfence
  • Better WP Security
  • Others

 

Note: We provide a solid baseline of security for all sites on Funnelcloud. For customers who want to go the extra mile, we always recommend keeping all plugins and themes up to date as older code has had more time to get cracked by the bad guys. Additionally, hiding your WordPress login, requiring a CAPTCHA or single-sign-on, having strong usernames and passwords all will help keep your site safe from the unsavory types on the web.

 

 

Related Post Plugins

In general, if you aren’t manually assigning related posts, any plugin that is automatically showing related posts is going to be doing so via a barrage of MySQL queries that happen on each and every page load. The end result is often a devastating hit on your site’s performance and substantial damage to your database.

Examples of disallowed Related Posts plugins:

  • Yet Another Related Posts Plugin
  • Contextual Related Posts
  • SEO Auto Links & Related Posts
  • Similar Posts

 

NOTE: Since crawling over all your posts and establishing connections automatically requires some a lot of horsepower, we’d recommend one of these external related post services to perform the same function without the performance consequences.

 

 

Jetpack Related Posts

  • Related Posts for WordPress
  • Contextly
  • Link Checker Plugins

 

Like some of the other listed plugin categories here, the ongoing jobs run by these plugins can be really taxing on your server and steal resources that your visitors need to view your site in a timely fashion.

Examples of disallowed Link Checker plugins:

  • Broken Link Checker
  • WP Broken Link Status Checker

 

Note: For most users, checking broken links is only needed for one-off audits. For this, we recommend an external service like Free Broken Link Checker which will crawl your site for broken links.

 

 

Plugins with known issues

SMTP email plugins tend to interfere with our server mail sending, and run the risk of preventing your site from sending any emails at all. This is specific to SMTP; other email plugins that don’t use SMTP are generally ok.

EWWW Image Optimizer and other plugins rely on the exec() function, which we disable for security purposes. We don’t have any issue with image optimization plugins in general, though; in fact, we encourage them, as long as they compress existing image files and don’t create duplicates (since that could fill up your site’s disk space very quickly).

Some recommended alternatives: Compress JPEG & PNG Images, EWWW Image Optimizer Cloud (which does not rely on the same function as the non-cloud version of EWWW Image Optimizer), Imagify and Kraken.io.

Any plugin that specifically modifies .htaccess will not work on Funnelcloud, since .htaccess is an Apache file and we run NGINX.

Similarly, any plugin that needs to write to the wp-config.php file will be unable to do so, although in most cases you can contact Funnelcloud support and we’ll be happy to work with you to put whatever you need in place.

 

 

Other things to watch out for

The TimThumb image resizing script is embedded in lots of older themes and plugins built from about 2000–2014, but it is no longer supported or updated, so it’s a vulnerability. Besides, it tends to break things on Funnelcloud anyway. Stick with the image optimization plugins recommended above.

Along with TimThumb, Sucuri reports that outdated versions of Gravity Forms and RevSlider contribute to a high number of security incidents and vulnerabilities with WordPress sites. This is largely because these plugins are frequently embedded in themes and aren’t updated. As long as your theme is kept up-to-date and you are running the latest versions of these plugins, you shouldn’t have issues, but it’s worth double-checking.

Note that certain plugins run database queries to work, and these interfere with caching, which will slow down a site. These include (but are not limited to) Broken Link Checker (which also doesn’t play well with Staging/cloning) and some “related posts” plugins.

 

NOTE:  We take this issue very seriously and try our best to strike a balance between freedom, security, and performance. If you have any issues, we’re happy to work with you to figure out the best solution for your site!

 

This is by no means an exhaustive list, but gives you a sense for the types of plugins that we strongly discourage and/or don’t allow. If you have any questions about a particular plugin and whether it is allowed, don’t hesitate to contact Funnelcloud support.
