The following is a list of plugins that can cause issues when configured or used in certain ways:

Cache Plugins

All cache plugins should be used with caution and with the knowledge that they will have to be configured in order to not cause major problems. 

Keep in mind that when a cache plugin performs incorrectly it will cause issues with MemberMouse. This is a result of the nature of caching itself which takes a snapshot of pages and other resources the first time they're loaded and then on future requests pulls them from the cache instead of grabbing them from the server. This works great for static pages and resources but if a page has any sort of dynamic functionality, like a lot of your pages will when you're using MemberMouse, you'll end up delivering an incorrect experience to your customers.

Here are some cache plugins to use with caution:

  • W3 Total Cache (download screenshots of a sample configuration)

  • WP Super Cache (download screenshots of a sample configuration)

  • SG Optimizer (used with SiteGround hosting) - When certain settings are selected, these can keep visitors on your site from entering data on the checkout page. This may be accompanied by login page "frozen" on Sending, though members will in fact be logged in if they navigate to another page.

    Here are the settings that should be disabled:

    1. SG Optimizer > Frontend Optimizations - "Minify JavaScript Files" and "Combine JavaScript Files" should be disabled.

    2. SG Optimizer > SuperCacher Controls - Dynamic Caching should be disabled.

If you're going to use a cache plugin make sure you configure it such that:

  • MemberMouse core pages are not cached.

  • Pages with GET parameters (i.e. x=y at the end of the URL) aren't cached.

  • Pages that use MemberMouse SmartTags are not cached. If you're using SmartTags in a widget that appears on multiple pages, you'll need to exclude all of these pages from being cached.

Broken Link Plugins

There are several plugins that are designed to comb through your site and locate broken links, or links that take users to pages that are no longer active. While not only placing a lot of strain on your WordPress database and slow down your site, these plugins can cause your SmartTags to not function properly.  You will likely see an error like the one listed below:

<a href="Invalid SmartTag Configuration: The 'type' attribute 'footPassword' is invalid for SmartTag MM_CorePage_Link." class="mm-forgot-password">Forgot Password</a>

And your SmartTags will not function. If you have this issue on your site, try deactivating:

  • Broken Link Checker

We understand that Google suggests checking for broken links on your site. A safer (and less taxing) alternative is a site like, which is not a plugin, and will provide the same results.
