 * Hi Ralf, thanks for the detailed description — it helped a lot!
   This isn’t caused
   by the captcha or JavaScript, but by the plugin’s IP protection / rate-limiting
   feature. Due to a bug in the timing calculation, from the 3rd submission on it
   incorrectly detects “submitting too fast” and blocks it — regardless of browser,
   because they all share the same IP.Immediate workaround: Plugin settings → IP
   protection. Either turn it off briefly, or set “Period between submits” to a 
   small value (e.g. 5 sec) and raise “Max retries”. That makes the problem go away
   right away.We’ll fix the underlying bug in the next update. If an IP has already
   been banned in the IP settings, you can clear it via “Reset IP logs/bans”.Thanks
   for reporting it — we’ll get it sorted!Best RegardsMarc

 * Hi,
   thanks for the reply.Strange, becaue i have the IP protection not enabled.
   You can see the error if you try to comment for example this article:[https://www.ralf-kerkhoff.de/grafik/on1-plugins-in-acdsee/](https://www.ralf-kerkhoff.de/grafik/on1-plugins-in-acdsee/)
   Without Javascript protection the math captcha works fine – with javascript protection
   on it throws therror.CheersRalf
