Had a 2.5.8 site where the integrated Capcha stopped working. Tried some things that others suggested, but nothing worked.
- Changed a line of code in the Recapcha php file as suggested in the Joomla Forum. Didn’t do anything.
- Regenerated new keys. Didn’t do a thing.
I got it fixed by updated my Joomla core install from 2.5.8 to 2.5.11 and the capcha was working again.
