RVsitebuilder doesn't support MySQL Strict Mode On, and your server has MySQL Strict Mode "On". Please disable MySQL Strict Mode by the following solution.

1. You can check by run the following command.

[root@system ~]# mysql

mysql> SELECT @@GLOBAL.sql_mode;
+--------------------------------------------+
| @@GLOBAL.sql_mode |
+--------------------------------------------+
| STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION |
+--------------------------------------------+

Output For MySQL 8.x
mysql> SELECT @@GLOBAL.sql_mode;
+-----------------------------------------------------------------------------------------------------------------------+
| @@GLOBAL.sql_mode |
+-----------------------------------------------------------------------------------------------------------------------+
| ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION |
+-----------------------------------------------------------------------------------------------------------------------+


2. Run the following command to disable MySQL strict mode please edit file my.cnf.

mysql> exit

[root@system ~]# nano -w /etc/my.cnf

[mysqld]
sql_mode = "NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

For MySQL 8.x
[mysqld]
sql_mode = "NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION"

4. restart MySQL service

[root@system ~]# /scripts/restartsrv_mysql

mysql> SELECT @@GLOBAL.sql_mode;

+--------------------------------------------+
| NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION |
+--------------------------------------------+
