Entering multiple queries causes Internal Server Error

[mike sherwood]

My hosting company recently upgraded my server to Ubuntu 20.04 and now adminer is acting weirdly. (not sure the upgrade has anything to do with this, but that's the thing that changed).

At any rate, the problem is easy to describe. If I enter one query, it works. if more than one it doesn't. For example:

The following queries by themselves work.
select * from my_users limit 1;
and this works
select * from coaches limit 1;

but when executing both, it doesn't
select * from my_users limit 1;
select * from coaches limit 1;

I get this error
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator to inform them of the time this error occurred, and the actions you performed just before this error.
More information about this error may be available in the server error log.

This is with mysql version 8

Thank you.
