If you update to Joomla 3.8.10, please make sure that you either do a full GitHub update of Fabrik, or disable caching for your lists (in the Advanced settings) or turn off Joomla's System Cache setting. A change in Joomla's cache code in 3.8.10 required a fix in Fabrik, which will be rolled in to the next release, but is currently only available in GitHub.

We will be performing an update of XenForo (the forum software use on this site) this afternoon, Fri 8/17/2018. The forums will be unavailable for a (hopefully!) short time.
