Thanks for your answer!
So like you said my code about use img was not the real problem. I created my app on glitch.com (where i use my Pandorabots’s API) and I give a phone number to my bot with Twilio, when I send a message with my phone (Android) from my text message (not a app) ...it goes to Twilio.com then goes on glitch.com…the bot read my message and after give me answer .
And when I used my Pandorabots’API I think i have to refresh all aiml files when i change something in my aiml files on Pandorabots.com so I have to say in my code in glitch.com which session I use on Pandorabots….I am not sure and I don’t really know how to process!! But the real problem is that it doesn’t load my new files…
