Some queries fail with sql_mode=only_full_group_by

I setup a directory site at Directory Pagol. But unfortunately getting 500 internal error.
My server configs:
Ubuntu 18.04
Apache 2.4.29
PHP 7.2.17
MySQL 5.7.26

I migrated the database, but when browsing the directory, got:

Slim Application Error
A website error has occurred. Sorry for the temporary inconvenience.

Have you checked you have the document root right? The Webserver has to serve the .../public folder, not the root folder. And does the database connection work for the db-user you are using?

Also, there are logfiles in the .../logs folder. They might give you a hint what's wrong.

Hi @karnakitab and thanks for using the Friendica Directory! Slim Application errors are logged in logs/http.log for browser access.

The ../logs/http.log error log is as follows:

Thanks, what database software are you using? It seems to be more restrictive than what I used to write this query on, triggering this error.

[MrPetovan]

Can you please pull the latest master and report if you still experience the same error when browsing your directory?

I already used the latest master version (git clone https://github.com/friendica/friendica-directory.git).
The database server is the default Ubuntu MySQL 5.7.26.

[AlfredSK]

There was an update... a0cfd33 That's why you were ask to please pull again. :-)

Thank you. It is working now at Directory.
