Hi.. i've read about the issue of captcha in this thread http://www.oxwall.org/forum/topic/15003 and i've checked and followed the instructions above
about phpinfo look at the attachment...
on point 2 about page /base/captcha/ i still receive no image (broken one) and i cannot find any problem.
for what i can see it worked since a couple of week ago.. then when i was not able to solve the problem i just installed re-captcha plugin to permit user subscription but now i've discovered that members cannot send message to other users 'cause system captcha (not the plugin i've installed) is required.
Other things i could check? do you think removing and reinstalling GD Support and free type support could be a solution ?
regards
