Since there was no support from you from the past few days. We dont make customers Suffer, we tried different quickstart SP Keynote. This we cannot update license details and also cannot save anything from backend and the pages from SP page builder shows empty. We cannot take the site offline, so we are altering configuration.php
Now i deleted all the templates and DESPERATELY waiting for your support, trying to understand what to do next.
Please let us know which WORKING template to install for my conference.
