Wondering why all of a sudden security image has stopped displaying.
GD2 library with ttf is enabled (always has been).
Running Joomla 2.5.15
DT Register: 2.7.18
Haven't done anything with this site in a long time other than some Akeeba Admin Tools tweaks
Firebug says the link of what appears to be a placeholder image is coming from: components/com_dtregister/captchasecurityimages.php?width=100&height=40&characters=5&rand1&rand1
Got the same problem.
The problem will be in the .htaccess file if you rollback your file the security image will work.
don't know where the HTACCESS is killing it
