Title: Errors Last modified: August 22, 2016 --- # Errors * [LenaX](https://wordpress.org/support/users/lenax/) * (@lenax) * [11 years, 8 months ago](https://wordpress.org/support/topic/errors-87/) * I uninstalled a theme that I was no longer interested in, and after that, WordPress has been giving a bunch of errors. I tried clearing my browsing data and cookies, and when I went to log back into my website, I got even more errors. My entire website shows the errors as well whenever I try to look at it, and I can no longer log back in. Any suggestions? these are the errors: * Warning: include_once(includes/custompost.php) [function.include-once]: failed to open stream: No such file or directory in /home/content/s/c/r/screcordings/ html/CREATIVE-CHROMOSOME/wp-content/themes/architekttheme/functions.php on line 498 * Warning: include_once() [function.include]: Failed opening ‘includes/custompost. php’ for inclusion (include_path=’.:/usr/local/php5/lib/php’) in /home/content/ s/c/r/screcordings/html/CREATIVE-CHROMOSOME/wp-content/themes/architekttheme/ functions.php on line 498 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/s/c/r/screcordings/html/CREATIVE-CHROMOSOME/wp-content/themes/ architekttheme/functions.php:498) in /home/content/s/c/r/screcordings/html/CREATIVE- CHROMOSOME/wp-login.php on line 418 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/s/c/r/screcordings/html/CREATIVE-CHROMOSOME/wp-content/themes/ architekttheme/functions.php:498) in /home/content/s/c/r/screcordings/html/CREATIVE- CHROMOSOME/wp-login.php on line 431 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/s/c/r/screcordings/html/CREATIVE-CHROMOSOME/wp-content/themes/ architekttheme/functions.php:498) in /home/content/s/c/r/screcordings/html/CREATIVE- CHROMOSOME/wp-includes/pluggable.php on line 913 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/s/c/r/screcordings/html/CREATIVE-CHROMOSOME/wp-content/themes/ architekttheme/functions.php:498) in /home/content/s/c/r/screcordings/html/CREATIVE- CHROMOSOME/wp-includes/pluggable.php on line 914 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/s/c/r/screcordings/html/CREATIVE-CHROMOSOME/wp-content/themes/ architekttheme/functions.php:498) in /home/content/s/c/r/screcordings/html/CREATIVE- CHROMOSOME/wp-includes/pluggable.php on line 915 Viewing 6 replies - 1 through 6 (of 6 total) * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [11 years, 8 months ago](https://wordpress.org/support/topic/errors-87/#post-5328470) * Try [manually resetting your plugins](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F). If that resolves the issue, reactivate each one individually until you find the cause. * If that does not resolve the issue, access your server via [FTP or SFTP](http://codex.wordpress.org/FTP_Clients), navigate to `/wp-content/themes/` and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule- out a theme-specific issue (theme functions can interfere like plugins). * Thread Starter [LenaX](https://wordpress.org/support/users/lenax/) * (@lenax) * [11 years, 8 months ago](https://wordpress.org/support/topic/errors-87/#post-5328558) * I can’t login to my wordpress to reset my plugins. The login page keeps reloading, displaying the same errors if not new ones. I’m going to try going through my hosting site and de-activating everything to see if that will do the trick. * [fmindlin](https://wordpress.org/support/users/fmindlin/) * (@fmindlin) * [11 years, 8 months ago](https://wordpress.org/support/topic/errors-87/#post-5328560) * I just updated the base to 4.0, then updated plugins, then on after trying to update themes, got a tiny 6 pt “error” in the upper left. Restored database from backup with phpMyAdmin per codex [https://codex.wordpress.org/Restoring_Your_Database_From_Backup](https://codex.wordpress.org/Restoring_Your_Database_From_Backup) and all worked. Then went into Dashboard, tried again to update themes, and same thing happened. Successfully restored again from backup, but do not want to try Themes updating again without some counsel. * Many thanks. * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [11 years, 8 months ago](https://wordpress.org/support/topic/errors-87/#post-5328564) * LenaX, please see the guide I linked to for resetting your plugins. You’ll notice that no Dashboard access is required. * fmindlin, please open your own thread about that: [https://wordpress.org/support/forum/how-to-and-troubleshooting#postform](https://wordpress.org/support/forum/how-to-and-troubleshooting#postform) * [Ivan](https://wordpress.org/support/users/ivanyordanov/) * (@ivanyordanov) * [11 years, 8 months ago](https://wordpress.org/support/topic/errors-87/#post-5328570) * Hello, * The same issue with headers already sent warning is fixed in the following topic: * [https://wordpress.org/support/topic/warning-cannot-modify-header-information-headers-already-sent-15?replies=8](https://wordpress.org/support/topic/warning-cannot-modify-header-information-headers-already-sent-15?replies=8) * The explanation is very good so you might want to review it. * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [11 years, 8 months ago](https://wordpress.org/support/topic/errors-87/#post-5328579) * In this case, the “Cannot modify header information – headers already sent” warnings are merely a symptom of the first two “include_once” failures. Once those are corrected, the headers warnings will go away.
