The two posts are helpful.
I have Admin5.cgi in my members directory. And there was a time that browsers could read and execute only. In working out the kinks in my installation, I changed so browsers coule read, execute, and write. I later changed so browsers could read, execute, write, and delete.
I'll look for the following files and delete them:
Admin5.cgi
holdmems.cgi
temp.file
I'll report back with the results.
Thank you for your help.
