Same problems here – ground to a halt a couple of weeks back and have had no success in getting the daily or weekly digests started again. Have tried flushing the TT stuff from the DB, resetting, reinstalling, disabling other plug-ins etc… to no avail.
@wfzimmerman @garyploski – what you were investigating sounded positive – did you both resolve this problem permanently and, if you did, would you be able to post a clear step-by-step solution for us all here please? Your posts above point to a few different steps, but it’s not quite clear (at least to me) what exactly you did to sort it out.
If possible, much appreciated!
