Firing up Pico after a fresh installation on my Synology Diskstation (DS218+) [DS] with DSM and "Web Station" (nginx, latest PHP) resulted in the following error:

Fatal error: Uncaught RuntimeException: Unable to load plugin '@eaDir' from '@eaDir/@eaDir.php': File not found in /volume1/web/vendor/picocms/pico/lib/Pico.php:671 Stack trace: #0 /volume1/web/vendor/picocms/pico/lib/Pico.php(552): Pico->loadLocalPlugins(Array) #1 /volume1/web/vendor/picocms/pico/lib/Pico.php(424): Pico->loadPlugins() #2 /volume1/web/index.php(39): Pico->run() #3 {main} thrown in /volume1/web/vendor/picocms/pico/lib/Pico.php on line 671

It seems the DiskStation makes these ominous @eaDir-directories visible in all sub(directories) of its shares. To prevent searching these quirky directories i'd suggest a "canonical path"-filter for plugins:
