I rolled back my PHP to 5.6 while I've been trying to trouble shoot this. My error is as follows:
<!-- The Mysqli extension is required for this adapter but the extension is not loaded -->
After I installed PHP 7.1 through my WHM Panel (using MultPHP), I went into easyapache 4, added the mysqli extension, and provisioned...but it still didn't solve the issue. Is there a step I'm missing here?
