As I have read somewhere LWE 1.1 can make HTTPS secured customized webpage but only support newest LOGO 8.3. I would like to ask how to revert or convert back to non secured normal HTTP as working with LOGO 8.2.

I try HTTPS secured site loaded into LOGO 8.2, it still work in unsecured mode HTTP with very slow loading. I need to convert or edit HTTPS back to HTTP then it might help loading faster, I think.

Please advice...

Hi,

check if the checkbox in tools/transfer/acess control is checked and install the certificate on your device. 

Information how to install the certificate you can find in the LOGO! 8.3 manual here.
