Hey there,

I am really sorry for the delay of this reply as it is a weekend for us here.

It seems like i was unable to edit the file through your FTP server, this is what i hitting :

Error:	Connection timed out after 20 seconds of inactivity

Error:	File transfer failed

By the way, I suspect something conflict with the page builder, for some reason when you access Easydiscuss category page, it will get trigger this plugin file JoomlaFolder/plugins/system/pagebuilder3/pagebuilder3.php, if i temporary rename this folder, it no longer hit that Javascript error.

Perhaps you can try edit that file and modify following code and see how it goes.

Find this LINE 443

            if ($option == 'com_rstbox')

Replace with

            if ($option == 'com_rstbox' || $option == 'com_easydiscuss')
