Works perfectly on localhost but I have an issue on the host site. When I click on the File Manager icon, I get a "Not authorized to view folder!" error. How do I fix this error - which folder is this referring to and what permissions are needed??

Hello,
Please provide a link to your page.

nittanyleathernecks.com/comm_t4t.php

Please send the Online Page Editor login details to: support@dmxzone.com

Can you please check if the following file is uploaded into the Docs folder of your website: list_authorize_for_dmxEditor

No. It's not there.

Please then make sure to upload the generated locally in your Docs folder 0-byte files to your server.

Sorry... I do not understand these instructions. Would you clarify, please?

In your local site root folder you have a folder called: Docs and you setup the file manager to use this folder.
Inside the Docs folder locally there should be several 0-byte files called:
list_authorize_for_dmxEditor, upload_authorize_for_dmxEditor etc..
Please upload all of these files manually to your server.

OK I've uploaded these... I'll try the Editor now and let you know what happens.

This worked!

Thanks for your help.
