Poor Quality Control

Since the switch from BestWebSoft to Simplywordpress, the quality of this plugin has gone downhill, with numerous problems or issues introduced with what seems like every update. I no longer recommend using this plugin.

For example:

  • Formidable Forms discontinued its Math Captcha integration plugin with this plugin because of breaking updates (like reversing “cptch” to “hctpc” in the code for no discernible reason in an update)
  • As of update 4.4.4 adds ~500 queries associated with visitor tracking or some other nonsense, with many repeated queries, adding over 100ms to every page generation time (not even Memcached could help)
  • Increasingly poor English wording and grammar, leading to possible confusion

Error update

The program worked for a long time, but today the capcha stopped working. had to disconnect it….

Excellent plugin but PHP files are being changed

Captcha is a really efficient and easy to use plugin.

I was about to recommend it, but recently I noticed changes in the PHP code, mentionning “BestWebSoft” instead of “SimplyWordpress”. Is the owner (SimplyWordpress) in the process of selling his plugin to BestWebSoft? That would be great to inform the users, because those changes in the code are generating warnings with WordFence.

So, at this point, I would not recommend to install Captcha anymore, until things have been clarified.


Works as intended. Less fancy than Google, but also less privacy questionable.
