How to fix "Headers already sent" error in PHP

Warning: Cannot modify header information - headers already sent by (output started at /home/******/public_html/wp-includes/functions.php:3198) in /home/*****/public_html/wp-includes/option.php on line 773
How To Fix ?
Something is writing to the output buffer in advance of WordPress try to set the headers, resulting in the error you see. Usually this is a space or other character at the beginning of one of your files (not option.php, this is the file trying to set a header(), the error is probably in your theme or wp-config.php).
Remove the code that is sending the text (whatever it may be) and the error will go away.

How to press "ALT+F4" using AutoIt [duplicate]

How to press "Ctrl+Shift+Q" in AutoIt
(2 answers)
Closed 4 years ago.
I am new in AutoIt. I have run the notepad by using the following code in AutoIt:
Run("notepad.exe")
Now I want to quit the application by using "ALT+F4". How to press "ALT+F4" with AutoIt tool?
You'll want to check out the documentation for AutoIt - which is pretty good. The one you're looking for is: https://www.autoitscript.com/autoit3/docs/functions/Send.htm Keep in mind that you want to make sure that the window is active or that you're targeting the window. With that, I recommend using this : https://www.autoitscript.com/autoit3/docs/functions/ControlSend.htm ControlSend() works in a similar way to Send() but it can send key strokes directly to a window/control, rather than just to the active window.
The following code for pressing "ALT+F4" should work in AutoIt:
Send("{ALT down}{F4 down}{F4 up}{ALT up}")
OR,
Send("!{F4}")
OR,
Send("!{F4}", 0)
How to cut and paste tabbed lines with auto indent set to on in vi [duplicate]
This question already has answers here: Turning off auto indent when pasting text into vim (25 answers) Closed 9 years ago. Not sure which stack exchange group this question goes so please move to the correct one if this is the wrong one. What's happening is if I highlight something with tabs/indents from one window/browser and want to paste it into vi, the formatting gets messed up. For example, I have the following in another window that I want to copy: "date_created" : "2013-06-06 21:12:31", "netdriver_duplex" : "Full", "mac_address" : "FA:16:3E:17:CC:E1", "interfaces" : "eth0,sit0", "processors" : null After I highlight it and paste it in vi, I get the following: "date_created" : "2013-06-06 21:12:31", "netdriver_duplex" : "Full", "mac_address" : "FA:16:3E:17:CC:E1", "interfaces" : "eth0,sit0", "processors" : null Someone told me auto-indent is messing me up and to run ESC-> :set noai Copy/Paste stuff ESC-> :set ai but this gets tiring after a while. Is there a workaround when pasting tabbed lines in vi with autoindent set to on or do I have to turn off auto-indent, paste, turn ai back on every time? Thanks in advance for your help.
You have to use, in normal mode :set paste Then you paste what you want. To comeback to your original setting, use, in normal mode :set nopaste

Add this code in wp-config.php on the first line: ob_start(); error_reporting(0);
See How_do_I_solve_the_Headers_already_sent_warning_problem? > FAQ Troubleshooting « WordPress Codex (This error) is usually because there are spaces, new lines, or other stuff before an opening <?php tag or after a closing ?> tag, typically in wp-config.php. Open the file with a plain text editor (like Notepad or BBEdit) and clear out the white space. Check that the very first characters are <?php and the very last characters are either NOT a PHP closing tag, or a closing tag ?> with no blank lines or spaces after it. (FYI, a PHP file can run fine without the closing ?> tag.) When saving, be sure the file encoding is not UTF-8 BOM but plain UTF-8 or any without the BOM suffix. And: This could be true about some other file too, so please check the error message, as it will list the specific file name where the error occurred. Replacing the faulty file with one from your most recent backup or one from a fresh WordPress download is your best bet. If the error message states: Warning: Cannot modify header information - headers already sent by (output started at /path/blog/wp-config.php:34) in /path/blog/wp-login.php on line 42, then the problem is at line #34 of wp-config.php, not line #42 of wp-login.php. In this scenario, line #42 of wp-login.php is the victim. It is being affected by the excess whitespace at line #34 of wp-config.php. If the error message states: Warning: Cannot modify header information - headers already sent by (output started at /path/wp-admin/admin-header.php:8) in /path/wp-admin/post.php on line 569, then the problem is at line #8 of admin-header.php, not line #569 of post.php. In this scenario, line #569 of post.php is the victim. It is being affected by the excess whitespace at line #8 of admin-header.php.
remove the excess blankspace /home/ya3mblog/public_html/wp-login.php in line 59.
In my case happened because from the Wordpress Rest API in the functions I was ending the job by doing echo json_encode($result); instead of the simple: return $result; Changing that.. worked!
What means digits in Stack Trace [duplicate]
This question already has answers here: Closed 14 years ago. Exact duplicate of this question. When you get an error in .Net application we got an a Stack Trace. For example [ADOException: cannot open connection] NHibernate.Impl.SessionFactoryImpl.OpenConnection() +153 Hibernate.AdoNet.ConnectionManager.GetConnection() +119 NHibernate.Impl.SessionImpl.get_Connection() +42 What do those digits mean?
The number indicates line of the error. If complied in release mode it refers to Microsoft Intermediate Language (MSIL) line in that function in the dll. If compiled in debug mode it refers to actual line in your code.
