You need to upgrade your DreamFactory instance – version 1.8 is very old. If you wish to stay in the 1.x family, here are the upgrade instructions. [https://github.com/dreamfactorysoftware/dsp-core/wiki/Product-Upgrades](https://github.com/dreamfactorysoftware/dsp-core/wiki/Product-Upgrades) If you wish to move to version 2, you will need to do a fresh install and migrate your settings and apps manually.
