Editing dates on a members profile is not always successful

[Rvice]

Describe the bug
With my really poor hosting provider running MySQL 5.7.44, there are lots of issues with the database not executing or returning quickly. Sometimes, the dates won't save at all and it's not clear if anything is happening. Sometimes, it'll go through, other times it won't.

I spent some time investigating and introduced some indicators of something happening and an error state. This at least gives feedback to the user. There's lots around CSFR tokens in the process.

To Reproduce
Steps to reproduce the behavior:

1. Go to a members roles
2. Click edit to change dates
3. Makes changes and press OK
4. In some instances, not 100% nothing happens. Using NetworkSolutions (formerly iPage) Basic Hosting shows the issue.

Expected behavior
I expect it to work, but if it doesn't, I expect feedback.

Screenshots

If nothing is happen, was the request sent successfully to the action-url and only the processing there is to slow to get an answer?

The request was not sent successfully. Waiting 10-15 minutes before a refresh to be sure results in the previous values being there.
