XF 2.0 Exception Occurs Upgrading from 1.5.23 to 2.0.12

I'm getting an exception while trying to upgrade from 1.5.23 to 2.0.12 using a MAMP/localhost test installation.

An exception occurred: [ParseError] syntax error, unexpected 'Fn' (T_FN), expecting identifier (T_STRING) or '{' in src/XF/Template/Compiler.php on line 8

Any ideas what's happening?

That version of XF uses a keyword that is reserved in PHP 7.4+. You would either want to upgrade to XF 2.1 or downgrade PHP.

Downgrading PHP worked! Thanks!
