Getting Error Code : 500

Yes i had enabled falcom caching after i activated the plugin (using wordfence since last 2 months). This problem started since yesterday morning (Indian Time). After I deactivated wordfence the problem did not occur any more

Will this issue go away when there is the next update of your plugin? I am not that technically well versed, I can copy paste my .htaccess, which my hosting provider had provided me before I deactivated wordfence, if that will be of any help.
