Hello
Any errors in espocrm log (data/logs), apache error log or in browser console?

Hello, I had a same problem -> I did upgrade 4.8.4 to 5.0.3. using the upgrade patch. After installing everything, the address simply said "Not Found", nothing else.
I tried to convert all the files rights at data-folder from 664 to 644 as it was said in earlier mail, but didn't change anything.

Is there anything what could be done?
