Title: database error – aagh! Last modified: August 20, 2016 --- # database error – aagh! * [redlid](https://wordpress.org/support/users/redlid/) * (@redlid) * [14 years, 9 months ago](https://wordpress.org/support/topic/database-error-aagh/) * Not sure what I did, or whether I did it. But I get this error * Warning: Cannot modify header information – headers already sent by (output started at /home/buderimq/public_html/wp-config.php:2) in /home/buderimq/public_html/ wp-includes/functions.php on line 3286 * This is after the thing threw an error saying the database needed a repair and to add a line of code to the config.php file, then click “repair” . . . it did all this, said all was good but puts this error at the top of the page. Any page you try to go to says the same thing. * Help! Does anyone have any idea how I can I recover from this?

I was playing about with a plugin and must have broken it. I ftp’d in and deleted the plugin directory but I fear it has jiggered something else up! * I did not touch any other files * I looked in the functions.php and see the missing ?> and left it. * Man I am freaking as we put a heap of work into this and am terrified it is lost * Thread Starter [redlid](https://wordpress.org/support/users/redlid/) * (@redlid) * [14 years, 9 months ago](https://wordpress.org/support/topic/database-error-aagh/#post-2291472) * OK I went in and saw a space before the opening php in the wp-config file and fixed it. Then it came up with this . . . One or more database tables are unavailable. The database may need to be repaired. * The word repaired was a link, so I clicked it and it said add a line to the wp- config file and reload the page. * define(‘WP_ALLOW_REPAIR’, true); * I did this and it ran through some stuff and it said all is good. So I reloaded the wp-admin page and now the error simply states in big black letters . . .

Please remove the following line from wp-config.php to prevent this page from being used by unauthorized users. define(‘WP_ALLOW_REPAIR’, true); * So it says all is good, but when I remove the allow repair line in wp-config. php it throws the database error line. * Any clues? * [Digital Raindrops](https://wordpress.org/support/users/adeptris/) * (@adeptris) * [14 years, 9 months ago](https://wordpress.org/support/topic/database-error-aagh/#post-2291475) * It looks like it only checks the wp- tables, it could be the bad plugin added code to wp-config.php or to .htaccess, check these files. * Check the MYSQL Connection strings in wp-config.php are correct, and for any whitespace. * HTH * David * Thread Starter [redlid](https://wordpress.org/support/users/redlid/) * (@redlid) * [14 years, 9 months ago](https://wordpress.org/support/topic/database-error-aagh/#post-2291477) * Thanks for your help Dave, I really appreciate it. Will see if the host can restore the database * Thread Starter [redlid](https://wordpress.org/support/users/redlid/) * (@redlid) * [14 years, 9 months ago](https://wordpress.org/support/topic/database-error-aagh/#post-2291480) * Just found out they did a total backup 10 hours ago, so I will just wipe it out and start again. sigh Viewing 8 replies - 1 through 8 (of 8 total) The topic ‘database error – aagh!’ is closed to new replies. ## Tags * [Database Error](https://wordpress.org/support/topic-tag/database-error/) * In: [Fixing WordPress](https://wordpress.org/support/forum/how-to-and-troubleshooting/) * 8 replies * 2 participants * Last reply from: [redlid](https://wordpress.org/support/users/redlid/) * Last activity: [14 years, 9 months ago](https://wordpress.org/support/topic/database-error-aagh/#post-2291480) * Status: not resolved ## Topics ### Topics with no replies ### Non-support topics ### Resolved topics ### Unresolved topics ### All topics
