1 we use community version .
2.Upgrade was done from 7.10 and all steps in guide was done
3. mysql 8.0.20 , case was checked on many browsers (opera,chrome, internet explorer)
4. i don`t see error/exceptions on server log
5. i will check it .
6. yes i did it .
One one remark that bpmn is correct because i use them in previous version and nothing was change here.
Please note that this version is not among the supported mysql versions (1) and IE is not supported any longer, only latest version of Edge, Chrome, and Firefox are supported (2).
Did you mention which server do you have or you have a spring boot setup?
Regarding point 5 I think this will give us the hint what went wrong, however please consider switching to database that is supported as we can not guarantee for the others as we haven’t tested them.
i check all point - with supported mysql version and bpmn is still not displayed . I run browser with developer mode and what i see is this error message when i call cockpit :
