No, sorry. The address that I entered on the website is still the same. But it seems that is not belonging to me, even if I carefully copy-pasted in from my 4.02 electrum wallet.
I have just checked my OS for viruses, fake apps etc. Nothing shows up
Apart from
1. A hacker hijacking your website or servers and then changing the address into his if your website's security is weak
2. Importation of your wallet using different address formats or derivation paths
3. Clipboard hijacking malware.
I don't see how it's a problem of electrum wallet.
