I have been having issues using templates in CiviMail. If you use the sample responsive newsletter template the draft cannot be saved. We get an "error: Sorry your information could not be saved"
With out the template no issues. I have tried with different sample templates and the issues are the same. I have also tried different sites. Not sure when this started. I know on one site it was all fine earlier this year.
Anyone experience anything similar?
CMS: WordPress & CiviCRM 4.6.21 (also tried in 4.7.10)
