PC-Nuke! v7.8.31 is also built on the PHP-Nuke engine, so I followed the instructions
to create "/includes/custom_files/custom_head.php" and "/blocks/block-Calendar.php". After uploading the files, I noticed my site no longer loads -- any page, including the Admin area. The site restores once I delete the "custom_head.php" file, so it is apparently part of the problem.
Should I be doing something else, code-wise? Perhaps like PostNuke, PC-Nuke! has just a few "tweeks" that require new Blocks to be also "tweeked" accordingly? I will also try the PC-Nuke! forums and see what they think.
Anybody try this block in PC-Nuke! already?
