Title: Topic add Error 2 Last modified: February 22, 2017 --- # Topic add Error 2 * Resolved [sugarsweetde](https://wordpress.org/support/users/sugarsweetde/) * (@sugarsweetde) * [9 years, 3 months ago](https://wordpress.org/support/topic/topic-add-error-2/) * Hello Support-Team, * I have the same problem like this thread [https://wordpress.org/support/topic/resolved-topic-add-error/](https://wordpress.org/support/topic/resolved-topic-add-error/). I also read the support post, but I do not understand the following “Please replace all wp_ prefixes in this code to your database table prefixes, if they are wp_ just use it as is:” * I am sorry, but I am a beginner. Could you explain it for an absolute beginner? * Your forum plug-in is great. Much better than bbpress. * Many thanks in advance. * Kind regards, Marion Viewing 8 replies - 1 through 8 (of 8 total) * Plugin Author [Tomdever](https://wordpress.org/support/users/tomdever/) * (@tomdever) * [9 years, 3 months ago](https://wordpress.org/support/topic/topic-add-error-2/#post-8837354) * I hope you’re familiar with your hosting service cPanel and you can open phpMyAdmin Database manager. If you open this you can see table list. Just copy one of table name and leave it here and I’ll provide the replaced SQL. * [aajaanron](https://wordpress.org/support/users/aajaanron/) * (@aajaanron) * [9 years, 3 months ago](https://wordpress.org/support/topic/topic-add-error-2/#post-8838794) * [@sugarsweetde](https://wordpress.org/support/users/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 * Thread Starter [sugarsweetde](https://wordpress.org/support/users/sugarsweetde/) * (@sugarsweetde) * [9 years, 3 months ago](https://wordpress.org/support/topic/topic-add-error-2/#post-8841445) * Thank you all for so much help. * I have found out, that some tables are missing in the SQL Database. Here is the link to see the screenshot: [http://prntscr.com/ecjjxr](http://prntscr.com/ecjjxr) * All tables have the “wp_” The following tables are missing: wp_wpforo_likes wp_wpforo_posts wp_wpforo_subscribes wp_wpforo_topics wp_wpforo_votes * How and where can I put in the missing tables? * Sorry for the maybe stupid question, but I am in the beginnung with work on that. * I would be happy for further help. * Thank you. * Marion * Thread Starter [sugarsweetde](https://wordpress.org/support/users/sugarsweetde/) * (@sugarsweetde) * [9 years, 3 months ago](https://wordpress.org/support/topic/topic-add-error-2/#post-8841493) * An addition question: * Have I put the SQL-code in the database start? I have made again 2 screenshots: * [http://prntscr.com/ecjrdg](http://prntscr.com/ecjrdg) [http://prntscr.com/ecjsxf](http://prntscr.com/ecjsxf) * In the second screenshot, is this the right place to put the SQL-code in and then push the OK-Button. * That’s it? * Thank you for help in advance.
