When trying to compile the 1.2 program I get the following error – undefined reference to `mbedtls_md5_starts’. I did find a ‘fix’ at GitHub for this that cleared up the compilation error, however, when I upload the program, I get no output at all. Everything seems to be working. I get the proper monitor output and my browser connects, there is just nothing there. Has anyone else run across this> Everything up until this point has worked perfectly. If it matters, I am using an HiLetGo ESP32 Dev board
Thanks
Jim

Hi.
You probably forgot to upload the filesystem image to the ESP32 board.
Check the section called “Uploading Filesystem Image”.

Let me know if this solved the issue.
Regards,
Sara

Well, that was a little embarrassing. You were absolutely correct. Sometimes I guess we are just a little too close to the problem to see your way through. I think I got so distracted with solving the compile error I just completely forgot that step. All is well now. Thanks for the help
