Is there a way to get the message logged the normal way but to stop the printing of the same message in the navigator whenever a Webmin module dies?
I have tried many possibilities but none of them works. What have Webmin community think of?
[ edit ]
In fact, standard output of webmin script are logged, but when the script output in error, this standard output is printed at web browser. I just want the webmin miniserver to print an error 500 message, which I could custom, not to print the content of the standard error, but only that script has failed.

Markdown to html, it showed error message "pandoc.exe: r-markdown-temp2.docx: openBinaryFile: permission denied (Permission denied)
Error: pandoc document conversion failed with error 1
Execution halted"
When I tried to install "htmltools" it also shows "Error in install.packages : Updating loaded packages".
How to solve the problem?
Check to make sure pandoc is installed, else install with installr::install.pandoc()
Delete or rename previously generated document(s). If you can find that / those document(s), you'll see (that it says) "Read Only", the default MS WORD document load status. Unless that status is removed (by deleting the document, for example, or by clicking on that status bar to change it), you can't have permission to overwrite it.
I think it might be a problem Mapping the network drive where the R project is stored. Check this post and this link
I'm using symfony 4, What does error stands for ?
Warning: SessionHandler::read(): open(/var/lib/php/sessions/sess_634q91mh896b6aa4jpjvlihmar, O_RDWR) failed: Permission denied (13)
When a user logs into a Symfony application, session information is stored on the web server. By default Symfony uses the native PHP session mechanism, storing session info in a file in /var/lib/php/sessions/ on Linux systems. Your error message is output by PHP and means it got a permissions error creating or re-opening a session file.
The error appears only intermittently because PHP removes old session files randomly about every 1/100th or 1/1000th page load. (On some Linux variants, old session files are removed by a cron job instead.)
https://symfony.com/doc/current/session.html says:
"some session expiration related options may not work as expected if other applications that write to the same directory have short max lifetime settings."
Try to avoid having multiple processes writing to the same sessions directory. I think I got the error message because both an Apache web server and php bin/console server:start were running at the same time. One process may have removed the other process's session file.
See PHP manual and Symfony manual for how to configure writing to separate directories. For example, I changed {Symfony directory}/config/packages/framework.yaml:
# Enables session support. Note that the session will ONLY be started if you read or write from it.
# Remove or comment this section to explicitly disable session support.
session:
# handler_id: ~
cookie_secure: auto
cookie_samesite: lax
handler_id: 'session.handler.native_file'
save_path: '%kernel.project_dir%/var/sessions/%kernel.environment%'
gc_probability: 100 # Run garbage collection always for
gc_divisor: 100 # investigating this problem only.
Another possibility is a problem in your Symfony code can cause the error message. The Symfony documentation says not to call the PHP session functions like session_start() directly since Symfony classes call them. A bug in my code caused an exception which I speculate caused the error message.

For those familiar with C code, see the PHP interpreter source code line that prints the error here
Hope this helps!
Not related to symfony 4, but you have to fix permissions in your /var/lib/php/sessions/ directory
I just launched a site and when I go to a non-existing page, I get a 500 Internal Server error instead of a 404 errror.
I was thinking that this was because I didn't have a 404.html page (just a guess), but I just created a 404.html page at the root and I still get 500 errors.
What should I do to make it so that when somebody types in a bad address they get redirected to my custom 404 error page?
There is no special stuff going on with my site, just HTML, CSS and a tiny bit of javaScript. Not a Rails app, not a Wordpress site, no PHP, etc. ..just HTML files on an Apache server.
The error I get when I go to a non-existing page or directory reads like this"
Internal Server Error
The server encountered an internal error or misconfiguration and was
unable to complete your request.
Please contact the server administrator,
webmaster#subdomain.domain.com and inform them of the time the
error occurred, and anything you might have done that may have caused
the error.
More information about this error may be available in the server error
log.
Additionally, a 500 Internal Server Error error was encountered while
trying to use an ErrorDocument to handle the request.
After you have the Error 500 problem solved you can create a custom 404 page by editing your .htaccess file you should have one in the root of your directory.
Open the file with a text editor and add this:
ErrorDocument 404 http://www.yourwebsite.com/404page.html
You could also create a custom Error 500 by changing the above code to suite your needs.
It's pretty self explanatory but the last part is the directory that users will be directed to after they receive a 404 error.
I am getting the following error when (re)starting my Yesod app on openshift:
server: InvalidYaml (Just (YamlException "Yaml file not found: xxx.xxx.xxx.xxx"))
Where xxx.xxx.xxx.xxx is an IP address. I did find a link to a Heroku+Yesod issue saying something about "removing an argument" but it didn't say from where, and of course the scripts/settings are going to be different in the case of OpenShift. Any ideas what this error is and how to get past it?
I'm assuming based on the question that you're using the standard scaffolding. If you look in the code, you'll find that uses loadAppSettingsArgs, which is described as:
Same as loadAppSettings, but get the list of runtime config files from the command line arguments.
If you don't want to pay attention to command line arguments, just replace the call to loadAppSettingsArgs with loadAppSettings [].
My Windows Store app keeps getting rejected from certification testing and I managed to reproduce a consequent crash when running appverif's LuaPriv-check. I get this output though:
AVRF: failed to create verifier log file \??\C:\Users\xx\AppVerifierLogs\yy.exe.0.dat (status C0000022)
Process Monitor tells me yy.exe got ACCESS DENIED on a CreateFile operation in this folder. I have set full access to all users (the user reported in the log was the same as the owner of the folder). I am running Visual Studio and Application Verifier as Administrator, but this does not seem to apply. What is the correct way of giving user xx full access to this folder on win8? I have attempted to use different log folders for appverify but with no success. Anyone else able to use this tool with Store-apps?
This post describes similar issues. Attempting to run AppVerif –sppath C:\MyLogsLocation as in the suggested workaround gives AVRF: Error: Incorrect image name: <
So does running appverif -enable handles locks -for myapp.exe -sppath c:\MyLogsLocation
It might be a bug in app verifier.

0xc000022 is STATUS_ACCESS_DENIED. The process doesn't actually have write permissions, even if it looks like it should. This MSDN blog explains there is a bug in App Verifier so even if you specify -sppath the value won't be honoured unless you first delete the %WINDIR%\system32\config\AppVerifierLogs\ folder.
