No Default DBMS (no replies)

Wampserver is installed on my Windows 10 machine and suddenly, at the bottom it says "***No Default DBMS***" with a red caution triangle (as in the screenshot below). In the same left-click window you can clearly see that MySQL is installed and selected as the default.

In my research I read some bits about changing the port, but that doesn't seem to be relevant to my situation. The "W" in the system tray is green and all services (apache, php, and mysql) are started.

***What is going on here? Why is this message appearing all of a sudden and none of my virtual hosts are working?*** Phpinfo() page is working fine, so I know that php, mysql, and apache are all working.

SPECS:

Following are specs and answers to question I suspect you might ask for clarity.

- Windows 10 Version 10.0.19042 Build 19042
- Wampserver 3.2.5 - 64 bit
- MySQL 5.7.14
- PHP 7.0.10
- phpMyAdmin 4.6.4
- "W" indicator is GREEN

I discovered "Create Wampserver Configuration Report" in TOOLS menu and generated the report.

After the part about virtual hosts I see this:

Neither MariaDB nor MySQL is configured as the default SGDB.
See Right-Click -> Help -> MariaDB - MySQL
--------- wampmanager.ini (Last 4 lines) --------
[Options]
AeTrayMode=64 Bits
AeTrayOldMode=64bit
AeTrayVersion=3.2.3.7

It seems like it may hold the key, but I'm unsure what it means exactly, or precisely what to do next.

How can I fix this issue?
