James and Tyler
Thanks for your input on resolving the issues. I am happy to report that the CAPTCHA feature is working as expected. The image is displayed with random letters and when they are entered everything works well. Time will tell if we are invaded with BOTs but so far none.
I suspect that the config.inc.php file specifies a higher level folder on a server. Maybe like the PKP one. Since I am on a shared server I had no control over the path to fonts nor could I install them in the usr folder.
So here was the solution that worked. I created a new folder in my OJS path called fonts. Using Tylers suggestion to upload the FreeSerif.ttf font file into this folder and repointing the captcha settings to this file with the path .../OJS/fonts/FreeSerif.ttf the captcha is working.
I have also done this in OCS and it works. The coding is slightly different as the path in our installation is ".../ocs/fonts...." instead of OCS (note case) and the path in ocs needs to have quotes.
So thanks to James and Tyler for a solution. The great thing about the PKP support forum is that with the people at PKP and us users we eventually work out a solution. It may take some time, but we always solve the issues.
