Jomres 9.9.11 has been released.

This version addresses an issue created by Joomla 3.8 and a change they have made to their version class. If you are expecting to use 3.8.0+ with Jomres we ask that you upgrade Jomres (and it's plugins, where appropriate) first, then upgrade Joomla afterwards for the most seamless upgrade. If you upgraded Joomla first, then please use the install from web tab in Joomla to re-install Jomres. This should not affect your existing data, and it will just upgrade you to the latest version that is able to adjust to the new version class in Joomla.

As well as this change there are a handful of other tweaks and fixes.
