Adminer 1.0.1 on i-MSCP 1.4.2 error code published on first view, then was OK

On an actual new install with
- debian 8.7
- php7.1
- i-mscp 1.4.2
- Adminer 1.0.1

Installation was OK.

But when first time calling from the left side menu I could see just below the top black bar 1-2 rows of php-error code. Well, sorry for a missing screenshot, but when calling a second time, this message has gone. No difference between calling as client or admin. Same behaviour at both apps, the SQLEditor and SQLAdminer screens. I will keep an eye on this app, may have been only an issue of running conditions. But nevertheless wanted to report.

After that error-flash working is OK.

It happened again.
Screenshot added.

Text is:

Clicking on "reload page" in Firefox made the text disapear permanently. For now

PHP configuration for the domain is "Do NOT show errors".

Well, I reinstalled this VM to get php7.1
Drupal needs it and a shop prefers it.

But I will add Adminer on an old machine, if that's ok for you. And will report here again.
