[CWB] CQPWeb Create minimal metadata table crashes

Mon Sep 19 20:21:53 CEST 2022

I've searched for *secure_file_priv* in /etc/mysql/mysql.conf.d/mysqld.cnf
and there is no instance of it, just in case I also searched in
/etc/php/8.1/apache2/php.ini and nothing too...
I've changed from false to
$mysql_has_file_access = true;
in /lib/defaults.inc.php and /lib/defaults.php:
and now the error has changed to something more weird:

Got error 'PHP message: PHP Fatal error:  Uncaught mysqli_sql_exception:
Access denied for user 'cqpusr'@'localhost' (using password: YES) in
/corptedig-glif/cqpweb/lib/sql-lib.php:211\nStack trace:\n#0

 thrown in /corptedig-glif/cqpweb/lib/sql-lib.php on line 211', referer:
http://corptedig-glif.upf.edu/cqpweb/bnc/index.php?ui=manageMetadata

I looked for the database configuration in lib/config.inc.php
and could enter mysql with the data stored there, I mean the mysqluser and
the mysqlpassword for the cqpwebdb. Just in case I granted again the
database to the same user, but I still get that same last error.
