FTP to the site, and get a copy of the active theme’s functions.php file. You’re going to edit it in a simple text editor (like notepad) and upload it back to the site. * Moderator [keesiemeijer](https://wordpress.org/support/users/keesiemeijer/) * (@keesiemeijer) * [14 years, 6 months ago](https://wordpress.org/support/topic/help-bad-bad-problem/#post-2368003) * Read the second link in my first reply. Download [Filezilla](http://filezilla-project.org/) and connect to your server. see instructions how to use Filezilla here: [http://codex.wordpress.org/Using_FileZilla](http://codex.wordpress.org/Using_FileZilla) * Download your theme’s functions.php with FileZilla, edit it and reupload it to your server * [govpatel](https://wordpress.org/support/users/govpatel/) * (@govpatel) * [14 years, 6 months ago](https://wordpress.org/support/topic/help-bad-bad-problem/#post-2368006) * there are few ways to reset your urls back and using functions.php is one of them, if you like to use other method is fine as well in end all you doing is resetting urls in database * Try directly in database using instructions here [http://codex.wordpress.org/Changing_The_Site_URL#Changing_the_URL_directly_in_the_database](http://codex.wordpress.org/Changing_The_Site_URL#Changing_the_URL_directly_in_the_database) * or if you prefer to see video [how to reset urls](http://gbpcentral.com/blog/videohow-to-change-urls-in-wordpress/) * Thread Starter [tomholman](https://wordpress.org/support/users/tomholman/) * (@tomholman) * [14 years, 6 months ago](https://wordpress.org/support/topic/help-bad-bad-problem/#post-2368019) * Ok ive done all this and nothings changed * Changing the URL directly in the database * If you know how to access phpMyAdmin on your host, then you can edit these values directly to get you up and running again. 1. Backup your database and save the copy off-site. 2. Login to phpMyAdmin. 3. Click the link to your Databases. 4. A list of your databases will appear. Choose the one that is your WordPress database. 5. All the tables in your database will appear on the screen. 6. From the list, look for wp_options. Note: The table prefix of wp_ may be different if you changed it when installing. 7. Click on the small icon indicated as Browse. 8. A screen will open with a list of the fields within the wp_options table. 9. Under the field option_name, scroll down and look for siteurl. 10. Click the Edit Field icon which usually is found at the far left at the beginning of the row. 11. The Edit Field window will appear. 12. In the input box for option_value, carefully change the URL information to the new address. 13. Verify this is correct and click Go to save the information. 14. You should be returned to your wp_options table. 15. Look for the home field in the table and click Edit Field. Note There are several pages of tables inside wp_options. Look for the > symbol to page through them. 16. In the input box for option_value, carefully change the URL information to the new address. 17. Verify this is correct and click Go to save the information. * Thread Starter [tomholman](https://wordpress.org/support/users/tomholman/) * (@tomholman) * [14 years, 6 months ago](https://wordpress.org/support/topic/help-bad-bad-problem/#post-2368026) * dont worry all fine now thanks guys for your help * [govpatel](https://wordpress.org/support/users/govpatel/) * (@govpatel) * [14 years, 6 months ago](https://wordpress.org/support/topic/help-bad-bad-problem/#post-2368030) * You are welcome Viewing 7 replies - 1 through 7 (of 7 total) The topic ‘HELP bad bad problem’ is closed to new replies. ## Tags * [fatal+error](https://wordpress.org/support/topic-tag/fatalerror/) * In: [Fixing WordPress](https://wordpress.org/support/forum/how-to-and-troubleshooting/) * 7 replies * 3 participants * Last reply from: [govpatel](https://wordpress.org/support/users/govpatel/) * Last activity: [14 years, 6 months ago](https://wordpress.org/support/topic/help-bad-bad-problem/#post-2368030) * Status: not resolved ## Topics ### Topics with no replies ### Non-support topics ### Resolved topics ### Unresolved topics ### All topics
