Thread:Project talk:Support desk/Fatal error: Call to unidefined function wLoadExtensionMessages() in C:\xampp\apps\mediawiki\htdocs\extensions\flowchartwiki\checkfchw.php on line 41/reply (8)

I figured out how to get the errors displayed. After commenting out another wfLoadExtensionMessages('checkfchw'); in checkfchw_body.php (line 27) it worked. I got the graph.
