nginx – php-fpm “Cannot modify header information” error

I have two docker containers linked by a docker network. One is running nginxinc/nginx-unprivileged and the other is running php:fpm. I have linked them together so that the php:fpm container handles running the php, however when the php tried to update the page I get a header error (shown below).

I saw a suggestion to check the output_buffering parameter inside php.ini, however mine is already set to 4096.

Does anyone have any idea where I may be missing something here?

This is the error I receive in the web browser:

Array ( (fullname) => dsd (suggestion) => da )
Warning: Cannot modify header information - headers already sent by (output started at /usr/share/nginx/html/action.php:17) in /usr/share/nginx/html/action.php on line 33

Here are my dockerfiles:

azure ad – Access Denied error After migrate on-prem Local AD SP Database to Sharepoint Farm joined to AzureAD DS

I have migrated Sharepoint 2013 Farm which is joined to Local AD DS to Sharepoint 2016 Farm joined to AzureAD DS.

Client wants to take full use of AzureAD DS and want to migrate sharepoint farm to Azure VMs connected to AzureAD DS.

I created a Sharepoint 2016 farm. created normal webapp/Site collection and is able to access as expected.

When I attach sharepoint 2013 DB after upgrade it gives access denied to those upgrade web app.
Do I need to do any changes to existing usernames as they has been now talking to AzureAD DS instead of Local AD.

ESXi esxcli Error: Unknown command or namespace vm process kill –t=soft –w=67909

I’m running ESXi 6.5 embedded host client. When i ssh into the system I can run esxcli vm process list and get the expected output:

   World ID: 67909
   Process ID: 0
   VMX Cartel ID: 67908
   UUID: someuuid
   Display Name: testserver1
   Config File: /vmfs/volumes/somelocation/testserver1/testserver1.vmx

But if i run esxcli vm process kill –t=soft –w=67909 I get the error Error: Unknown command or namespace vm process kill –t=soft –w=67909

To confirm i’m running the correct command, i ran esxcli vm process kill -help and get

Error: Invalid option -h

Usage: esxcli vm process kill (cmd options)

  kill                  Used to forcibly kill Virtual Machines that are stuck and not responding to normal stop operations.

Cmd options:
  -t|--type=<str>       The type of kill operation to attempt. There are three types of VM kills that can be attempted:   (soft, hard, force). Users should always
                        attempt 'soft' kills first, which will give the VMX process a chance to shutdown cleanly (like kill or kill -SIGTERM). If that does not work
                        move to 'hard' kills which will shutdown the process immediately (like kill -9 or kill -SIGKILL). 'force' should be used as a last resort
                        attempt to kill the VM. If all three fail then a reboot is required. (required)
  -w|--world-id=<long>  The World ID of the Virtual Machine to kill. This can be obtained from the 'vm process list' command (required)

Can you see anything i’m doing wrong that might be preventing this command from working?
I realize there’s vim-cmd alternative in docs but i’m trying to figure out why the first option from the docs is responding like it’s not even a valid command.

sharepoint on prem – Error when opening Office documents from library through native client

We have a strange error on a Sharepoint 2013 farm since a few days. Opening documents using any native Office 2016 client (e.g. Word) does not work anymore. It shows the error below and they do not open at all. The documents can be opened in Web App mode however.

“There are network issues stopping us from opening your document. Please try again later.”

Any idea ?

applescript – My Apple Script Editor code doesn’t work gives “Syntax Error Expected end of line but found identifier.”

The problem is the version of Evernote I tried is not AppleScript scriptable.

When trying to add Evernote to the Library in Script Editor, in order to review its AppleScript dictionary, it errs with: Add Item Unable to add the item because it is not scriptable.

Additionally, when running the following command in Script Editor:

tell application "System Events" to ¬
    get has scripting terminology of application process "Evernote"

Its result is: false

Apparently at one time Evernote was AppleScript scriptable, however, in macOS Catalina, testing with Evernote from and checking Evernote > About Evernote it shows:

10.11.5-mac-ddl-public (2530)
Editor: v121.2.15734
Service: v1.32.4
© 2019 – 2021 Evernote Corporation. All rights reserved

Looking for the typical AppleScript dictionary in /Applications/ there is no Evernote.sdef files as would be expected if it was fully AppleScript scriptable.

If you do have a version of Evernote that is AppleScript scriptable then try the following, which I cannot test under the circumstances:

Change note1 to note in:

set myNote to create note1 with text myTitle title myTitle notebook "Imported Notes" tags ("imported_from_notes")

You might also want to put in some parentheses. e.g.

set myNote to (create note with text myTitle title myTitle notebook "Imported Notes" tags ("imported_from_notes"))

Unfortunately without a version of Evernote that is AppleScript scriptable, I cannot offer more.

rom flashing – Heimdall Error (PIT file)

I a have a PC running Lubuntu 16.04.06. I installed heimdall 1.4.1 in order to flash a custom recovery. It always fails to download the PIT file, part #16 to be specific. I tried multiple devices and it just gives the same error. I also tried JOdin3 before but it wouldn’t run when I execute the binary. Is it possible to fix this error I keep getting in heimdall? or does anyone have a heimdall build that’s working?
