I can send a single SMS in 4.7.11 using Clickatell. But a mass SMS fails with the following message from the cron task 'finished execution of Send Scheduled SMS with result: Failure, Error message: DB Error: syntax error'. I have installed version 3.0 of the Clickatell extension from Veda Consulting. Anyone know if this extension is supported in 4.7? Any comments?
Looks like fix is not present in v4.7.11. But there is a ticket already - https://issues.civicrm.org/jira/browse/CRM-19327. Might be available in v4.7.12.
Anyway seems like a minor patch to apply?
