Note: For detailed error information (necessary for troubleshooting), enable "DEBUG mode". To enable "DEBUG mode", open up the file include/essentials.php in a text editor and locate the line "//define(\'PUN_DEBUG\', 1);". It it located at the very top of the file below the software license preamble. Then remove the two slashes in the beginning of the line and save/upload the script. Once you\'ve solved the problem, it is recommended that "DEBUG mode" be turned off again (just add the two slashes back again).
