Hi, I'm using Moodle 2.5.5 and i tried adding a plugin namely: Block: moodletxt - bbconnecttxt.com SMS/Text Two-Way Messaging Module(Version 3.0.6) for sms sending purposes which i've downloaded from your website.

The plugin passed the validation test so i clicked on "Install Add-on" after that there's this error : "Coding error detected, it must be fixed by a programmer: Trying to reference an unknown block region side-post".

Anyone or anything that can help me (to send sms from my moodle to all selected users) with this, is very much appreciated...

Or any other options just to accomplish the abovementioned problem....???
