Fatal Error Upon Activation

Hi. I tried your plugin last week and loved it.

However, when I just added it again today and activated, it’s triggering a fatal error. Appears to be an issue after the last update. The previous version worked fine. Details below:

Fatal Error: Cannot declare class class_fma_lang, because the name is already in use in —/wp-content/plugins/file-manager-advanced/application/class_fma_lang.php on line 9
