I read, I did everything as written, but it is still not working and when I click on generate the flight plan nothing happened, but I already have the api and put it in the right place, also uninstalled and installed everything again several leaks. One of the main mistakes is this (Warning: simplexml_load_file(): http://www.simbrief.com/ofp/flightplans/xml/:1: parser error : Document is empty in /storage/ssd2/921/2877921/public_html/core/modules/SimBrief/SimBrief.php on line 12) and the button that does not work. Pls help-me @Vangelis
