Remove each text widget and PHP widget( copy the content into a text editor so you can retrieve it afterwards again). Go back into your wp-config.php file and remove the comments again. Save. Log in and add your text widgets again. This should work fine now. * [beritany](https://wordpress.org/support/users/beritany/) * (@beritany) * [17 years, 7 months ago](https://wordpress.org/support/topic/warning-array_keys-functionarray-keys/page/2/#post-751880) * here’s what comes to my blog after i tried to log-in * Warning: array_keys() [function.array-keys]: The first argument should be an array in /home/beritany/public_html/wp-includes/widgets.php on line 686 * Warning: Invalid argument supplied for foreach() in /home/beritany/public_html/ wp-includes/widgets.php on line 686 * Warning: Cannot modify header information – headers already sent by (output started at /home/beritany/public_html/wp-includes/widgets.php:686) in /home/beritany/ public_html/wp-login.php on line 267 * Warning: Cannot modify header information – headers already sent by (output started at /home/beritany/public_html/wp-includes/widgets.php:686) in /home/beritany/ public_html/wp-login.php on line 279 * Warning: Cannot modify header information – headers already sent by (output started at /home/beritany/public_html/wp-includes/widgets.php:686) in /home/beritany/ public_html/wp-includes/pluggable.php on line 595 * Warning: Cannot modify header information – headers already sent by (output started at /home/beritany/public_html/wp-includes/widgets.php:686) in /home/beritany/ public_html/wp-includes/pluggable.php on line 596 * Warning: Cannot modify header information – headers already sent by (output started at /home/beritany/public_html/wp-includes/widgets.php:686) in /home/beritany/ public_html/wp-includes/pluggable.php on line 597 * Warning: Cannot modify header information – headers already sent by (output started at /home/beritany/public_html/wp-includes/widgets.php:686) in /home/beritany/ public_html/wp-includes/pluggable.php on line 770 * can anyone help me? i cant log in, i cant remove my widgets, and i dont even know what mistakes that i made…. * [philsouthwark](https://wordpress.org/support/users/philsouthwark/) * (@philsouthwark) * [17 years, 7 months ago](https://wordpress.org/support/topic/warning-array_keys-functionarray-keys/page/2/#post-751882) * Same here – I added a text widget and immediately was inundated with the same error as above. * But all the widgets disappeared at the same time so there are none to delete. * I have tried commenting out the lines suggested.

I know why I hate to update WordPress, I have no idea what to try next, if this is just a text widget problem I could fix it easily if I had access to the admin panel. * Still need help if anyone can help…… * [dukeofdordogne](https://wordpress.org/support/users/dukeofdordogne/) * (@dukeofdordogne) * [17 years, 5 months ago](https://wordpress.org/support/topic/warning-array_keys-functionarray-keys/page/2/#post-751890) * I had the exact same problem / error, although mine was with a fresh install.

Not sure what to try next, maybe going back in and taking the text code out of the header and deleting all comments this would leave no text errors possible, maybe upgraded or deactivate all the plug ins.
