Rick,
I have been having a similar problem in my attempts to install pmachine pro 2.4.1. I successfully create the tables, but then the next step I receive the following message:
Fatal error: Call to undefined function: realpath() in /data/4/0/128/49/291864/user/296375/htdocs/Blogging/pm/install.php on line 1763
This happens on install.php?page=5 part of the setup. But I double checked and I did upload all the files.
Line 1763 of the install.php is:
$add = new DB_query($result, “INSERT INTO {$dbprefix}_prefs VALUES (’’, ‘45’, ‘120’, ‘t’, ‘captcha_relative’, ‘“.realpath(’../images/captchas/’).“‘,’830’)”,"0"); if(!$add->result) $error =1;
As an experiment, I deleted this line and re-ran the install.php. The site installed “successfully” but I’m sure that line of code i delete wasn’t there just to look pretty. I imagine I’ll find out the hard way sooner or later what that line does (I’m code-illiterate), unless you can help?
