I just installed the plugin and received this error message once activated.
Warning: opendir(D:\Temp,D:\Temp): Access is denied. (code: 5) in D:\home\mysite.com\wwwroot\wp-content\plugins\formidablepro-2-pdf\fpropdf.php on line 143 Warning: opendir(D:\Temp): failed to open dir: No such file or directory in D:\home\mysite.com\wwwroot\wp-content\plugins\formidablepro-2-pdf\fpropdf.php on line 143
For your information, I have also the same problem. Here is the error message “Formidable PRO2PDF: Folder /home/lapataubone/web/kampuslapataubone.ac.id/public_html//tmp/ should be writable. Please change its permissions to 777. Can not open a temporary file for writing, verify the permissions.”
I created a TEMP folder under public_html (WP root) and set permission to 777 but it does not solve the problem.
Instead, I created a TMP folder (Not TEMP folder) under public_html and set permission to 777 and it solved mu problem.
