@sugarsweetde – I’m just another user but maybe this will help.
When you set up WordPress it has a file called wp-config.php and inside that file which you edit from your host file manager cPanel or using an FTP client to download and edit, you can scroll down past the secret keys in the file and you will see a section that says:
/**
* WordPress Database Table prefix.
*
* You can have multiple installations in one database if you give each
* a unique prefix. Only numbers, letters, and underscores please!
*/
$table_prefix = 'wp_'; (or whatever is between the single quotes)
So when you go to your website host cPanel and under “Website” open the “MySQL” link and then you see databases with crazy names. (If more than 1 then use the one you also see higher up in the wp-config.php file ). To the right click on the door icon to access the database and in the left side list you can see the tables with the prefix – probably wp_ – before everything.
The letters AND the _ underscore are what you need to work with.
In the end the prefix back in the wp-config "$table_prefix = 'wp_';
`. has to match the one in you database
So if your table prefix is NOT wp_ you have to use your desktop/laptop/whatever text editor to search and replace wp_ in the script text from the post links you refer to (for example in the line …CREATE TABLE IF NOT EXISTS wp_wpforo_subscribes …) and replace it with the prefix in your wp-config. save it and then run that script as instructed in the post
Running the SQL is done inside the open database.
I hope I got the right idea about your problem – hope this helps
