Dear all：
Current version 10.7.5
I succeeded from 10.7.5->10.8.7
When I click on settings appear
Please help me…
Hi,
check the production logs on your server, http 500 errors always involve server side problems.
Also, I don’t know whether 10.x is still supported. I’d suggest upgrading to 12.x after solving this issue.
Cheers,
Michael
