$ php admin/cli/mysql_compressed_rows.php
Script for detection of row size problems in MySQL InnoDB tables.
By default InnoDB storage table is using legacy Antelope file format
which has major restriction on database row size.
Use this script to detect and fix database tables with potential data
overflow problems.
Options:
-i, --info Show database information
-l, --list List problematic tables
-f, --fix Attempt to fix all tables (requires SUPER privilege)
-s, --showsql Print SQL statements for fixing of tables
-h, --help Print out this help
Example:
$ sudo -u www-data /usr/bin/php admin/cli/mysql_compressed_rows.php -l
$ php admin/cli/mysql_compressed_rows.php -l
mdl_data Compact (needs fixing)
mdl_data_fields Compact (needs fixing)
mdl_enrol_paypal Compact (needs fixing)
mdl_lti Compact (needs fixing)
mdl_user Compact (needs fixing)
mdl_user_info_field Compact (needs fixing)
$ php admin/cli/mysql_compressed_rows.php -f
Cannot enable GLOBAL innodb_file_per_table setting, use --showsql option and execute the statements manually.!!! Error writing to database !!!
$ php admin/cli/mysql_compressed_rows.php -s
Copy the following SQL statements and execute them using account with SUPER privilege:
====================================DESDE ACA ===================================================
USE moodle27;

SET GLOBAL innodb_file_per_table=1;

============Esta prueba debe pasar Para el soporte completo de UTF-8 en MySQL y MariaDB se requiere cambiar la opción de MySQL 'innodb_large_prefix' a 'ON'. ==============
Juan Carlos,
Quizá te sirva esta página: http://stackoverflow.com/questions/35847015/mysql-change-innodb-large-prefix
Sobre todo la parte donde pone
mysql > set global innodb_file_format = BARRACUDA;
mysql > set global innodb_large_prefix = ON;
Posiblemente puedas ejecutar esas órdenes sql desde phpmyadmin si tu usuario tiene permisos de escritura en la base de datos.
Si no es posible, deberás solicitar su modificación al servicio técnico del hosting, tal como te han aconsejado, o buscar otro que se adapte mejor a Moodle en cuanto a que se te permita el acceso root al sitio.
Un saludo
JP
