Getting a 500 error on the front end with PHP 7. It's fine with PHP 5.6.30 though. Nothing in the error log. MODX version 2.5.6

Did you get this error after upgrading to PHP 7 on existing MODX installation?

Did you clear the cache by deleting all folders in CORE/CACHE folder after upgrading to PHP 7?

I didn't, but I just tried and it didn't make any difference.

This is a tough one. In my experience, the most likely cause is a plugin that contains a function that was previously deprecated and is now removed in PHP 7 or code that no longer works in PHP 7. It could also be a snippet, but that will usually leave something in the error log.
There's some PHP 7 compatibility info here:
http://php.net/manual/en/migration70.incompatible.php.
It might be easier to just disable all your plugins in the DB (modx_plugins table) -- and clear the cache manually again -- to see if that fixes it. If it does, activate them one at a time until it breaks to see which one is the culprit.
