Hi!
When trying to activate Fontsampler v0.4.5 on freshly installed WordPress 5.3.2, getting the next error:
Plugin could not be activated because it triggered a fatal error.
Parse error: syntax error, unexpected '::' (T_PAAMAYIM_NEKUDOTAYIM) in /home/xxxxxxxxx/xxxxxxxxxxxxxx.com/wp-content/plugins/fontsampler/FontsamplerDatabase.php on line 662
