Seem to have lost your reply on this. Also your site does not seem to have stored my recent question. Here is a page I set up with plugin when you visit the inital page it looks ok
Try clicking on knowledgebase
and you will get
Sorry this doesn’t look like a WHMCS site at [http://www.2001web.com/support/] Make sure your WHMCS Integration settings are pointing to the correct URL and that the WHMCS site is set for the Portal template in Setup | General.
That URL is correct.
Here are the settings I have in admin
Remote WHMCS host: http://www.2001web.com/support/
Default content page: whmcs
URL to encode: nothing in here as i do not know what to put in here there is no documentation on this. Even the screen shots in your documentation do not show this field perhaps they need updating.
Any help would be appreciated.
