Enhance your website's security with EasyCalcCheck Plus, a powerful plugin to protect your registration and contact forms from spam threats. This plugin works by incorporating a simple arithmetic task, a feature known to deter spambots effectively.

For added security, the plugin allows you to activate a hidden field and impose a time limit for form submission. The hidden input field is particularly effective against spambots, which typically fill in every available field, hidden or not, whereas regular users do not see or interact with it. The time limit further bolsters protection by restricting too-fast submissions, a common characteristic of bot activity.

When internal spam protection falls short, EasyCalcCheck Plus integrates seamlessly with external anti-spam services like Akismet, Mollom, and others.

But the utility of EasyCalcCheck Plus extends beyond spam protection. It offers backend security via a token system and guards against SQL injection threats, delivering a comprehensive security solution for your site.

EasyCalcCheck Plus has been honed and improved over several years, incorporating support for popular form components like FoxContact, Kunena Forum, FlexiContact, and DFContact. Its adaptable design allows for quick and easy extension to other components, offering a robust defence against spam messages and registrations caused by spambots.

As a testament to its effectiveness, EasyCalcCheck Plus holds a top position in the captcha category on Joomla! Extension Directory. Thanks to its continual development, optimization, and user-centric approach, it ranks among the best-rated extensions overall.

The plugin's continuous development journey includes bug fixes and the addition of support for various 3rd party extensions, such as ALFContact, JomSocial, and Virtuemart.

Choose EasyCalcCheck Plus to secure your website and enjoy a spam-free, seamless user experience.

Install the plugin by accessing the administration menu of the back-end under Extensions. Then access Extensions – Plugins – System – EasyCalcCheck PLUS and customize it to your needs. Don't forget to activate it!

In the beginning, I recommend using the standard settings. If some spam still gets through, you should consider activating an external service like Akismet.

Enjoy! ;-) Spam is finally a thing of the past!

Spambots shouldn't be stopped only by ECC+ on the client-side. The majority of spambots is easily identified with the help of blacklists and prevents proactive the loading of your website. Since version 1.5-7 bots can be identified and blocked by comparing the actual blacklist from Honeypot Project or StopForumSpam.

In addition, comprehensive anti-spam services like Akismet, Mollom, reCaptcha and Botscout have been implemented to recognize and filter spam even better!

Tip: This website and all my demo sites did not receive any entries or registrations through spambots with the following configuration: arithmetic problem, hidden field, time lock and Akismet. If this configuration is not enough, then another spam service can be activated additionally.

Note: EasyCalcCheck Plus is a system plugin and not a plugin from the Captcha group. The option "Default Captcha" in the global configuration and the settings of the user management should be deactivated. Use EasyCalcCheck Captcha if you want to have a plugin using the Captcha group!

Latest release

Version - 2024-05-13

  • + Subscriber Interface: The plugin has been rewritten to utilise the subscriber interface, enhancing its integration and performance capabilities.
  • + Improved Pro Security Token validation check. The Pro package contains a token file with an individual security token linked to the user account that is checked against the validation server for authenticity. If the file is missing or the token is invalid, you cannot edit the settings and use the extension. The Pro Security Token field has been extended to handle incorrect tokens and blocked accounts. If you encounter an error message related to the token, download the Pro version with your Pro subscription from the linked download page and install it again!
  • Attention: The Pro extension will not work correctly if the token file or custom field is missing or modified. Never edit or remove the files to ensure correct functionality.
  • + This major update involves fundamental changes to the plugin architecture to improve efficiency and modularity. The new minimum required Joomla! version has been increased to 5.1.0.
