That looks promising. Thank you Rene
In our case there were over 22.000 files in the folder \wp-content\uploads\wpcf7_captcha\
after we deleted these, the site was faster again.
Is is possible to use only 10 or 25 random keys? Generating and (saving/loading) over 11.000 keys is a bit silly. And Slow.
Would you guys please explain where I should change this code?
I can’t get it to work… feel like such a noob. 🙂
