Apache 2.4 on Windows 10 PRO

Is this a bug in the templates_actionCommon.twig plugin?

ERROR Piwik\FrontController[2022-09-17 00:53:55 UTC] [d2725] Uncaught exception: C:\www\matomo\plugins\Live\templates_actionCommon.twig(25): The string to escape is not a valid UTF-8 string.

Or am I missing something in the php.ini file?

UPDATE: I since added “Authenticated User” to the Security Group and the Failed to write cache file error is now no more. But on /index.php?module=CoreHome&action=index&date=previous30&period=range&idSite=2#?idSite=2&period=range&date=previous30&category=General_Visitors&subcategory=Live_VisitorLog I am still getting this error:

Hi,
Do you have some “exotic” char in your tracking, like accents, Cyrillic chars, etc?
How is configured the database charset?

3

Database Collation is set to utf8mb4_general_ci

Yes - it is possible that I may have accents in setDocumentTitle. I use:

var _paq = _paq || ;
_paq.push([“setDocumentTitle”,“<%= TitleContentHolder %>”]);
…

where TitleContentHolder may include French or other “exotic” characters.

To note is that it is the page “Visitors > Visits Log” that produces

Oops… there was a problem during the request. Maybe the server had a temporary issue, or maybe you requested a report with too much data. Please try again. If this error occurs repeatedly please contact your Matomo administrator for assistance.

And if I go to “Visitors > Locations” I get the error too, but after several page refresh I finally see the errors go away.

I am still – occasionally – getting

\CoreHome\templates_dataTableFooter.twig(21): An exception has been thrown during the rendering of a template ("Failed to write cache file

4

Looking at the Network tab I see that I get 500 Internal Server Errors on these pages with these errors.

@innocraft do you have some clues?

I just got this (hope it helps)

ERROR Piwik\ExceptionHandler[2022-09-20 16:18:09 UTC] [f5c24] Uncaught exception: C:\www\matomo\vendor\twig\twig\src\Cache\FilesystemCache.php(76): Failed to write cache file “C:\www\matomo/tmp/templates_c/8b/8b0854839659e496ee6fc33db6686b6e.php”.

It looks like PHP is just not having the proper permissions to use C:\www\matomo/tmp to write files to.

Could it be that it has to do with my setup? I have 2 PHP running side by side. One for IIS (php-8.1.10-nts-Win32-vs16-x64) and one for Apache (php-8.1.10-Win32-vs16-x64). They are configured separately and kept apart.

7

And just got these:

Error in Matomo: The date 'today' is not a correct date range. It should have the following format: 'lastN', 'previousN', 'YYYY-MM-DD,YYYY-MM-DD'.

Error in Matomo: Failed to write cache file "C:\www\matomo/tmp/templates_c/8b/8a0854839659c496ee6fc33db6686b6e.php".

Error in Matomo: The file : can not be opened in write mode.

And I forgot to mention, the error only happens with site ID 2. No errors that I know of with the other sites. Site 1 has much more traffic; 2 has not much at all.

Hi @courtens Matomo may in rare cases display an error such as ‘Oops… there was a problem during the request.’ or ‘Internal Server Error’ or ‘500 error’.

When you have such problem, please follow the following steps to resolve the issue:

  1. The most common solution to the message Oops... there was a problem during the request. is to setup Auto-Archiving in your Matomo by following these two steps:
    a) Enabling the crontab to run the core:archive command and
    b) Disabling “Archive reports when viewed from the browser” in the General Settings.
  2. If the error persists, or you’re getting a white screen/page (sometimes called the ‘White screen of death’), it indicates that there is a problem on the server: check in your web server error log file for an error message.

Thank you for that information V.K.

Please find above my errors I am getting. The error is “persisting” :roll_eyes:

I have the same error, but am using the wordpress plugin. Those instructions say If you are using Matomo for WordPress , you don’t need to do this as it utilises the WP Cron

I have posted twice asking for help on this and its for a client. I really need to get it sorted. I hate to hijack someone elses post, but I need answers as well

I updated to 4.12.1 and the error persists. Finally the “Visit in real-time” is working for the troubled domain name, but “Visits Log” is still returning “Oops… there was a problem during the request.”

I followed your suggestion of disabling “Archive reports when viewed from the browser” in the General Settings, and have setup Windows: How to Set up Auto-Archiving Using Windows Scheduler.

At a closer look it looks to me like it could be a Windows back-slash forward-slash problem in the way C:\matomo/tmp/templates_c/ce/cee8a44a4cabd76257f3dda3e3b87061.php it trying to write the temp file. But this would be odd - because it would not explain why just that on domain name has the problem, all the other domain names do not have that problem.

12

Do they use the same Matomo files (at the same location)?
Maybe one “server” blocks the other one…

13

@heurteph-ei
Do they use the same Matomo files (at the same location)?
Maybe one “server” blocks the other one…

The installs are separate. Apache calls use one, IIS uses the other PHP install. Matomo is configured to use direct request from Apache server.

What is strange is that it is just one account that has that problem. The others work well.

14

Then if I understand well, the 2 instances are installed on separated physical or virtual servers (not on the same one)?
It seems there is some right access problem in one of your configurations… Why not installing both with the same config (the one that works! :wink: )

15

The two instances are installed on the same physical server. I am running Apache directly and IIS calls via Apache proxy. But this should not matter … I think … because the error only appears on ONE of the websites. None of the others have that problem.

I just updates to the latest update
Matomo version: 4.12.3
MySQL version: 10.6.5-MariaDB
PHP version: 8.1.10

And I am still getting that error with that ONE PARTICULAR SITE on the page: Visitors > “Visits Log” (category=General_Visitors&subcategory=Live_VisitorLog). The similar page on (category=Dashboard_Dashboard) “Visits in real-time” works.
As explained above – none of the other sites have that error on “Visits Log”.

16

I get error:

Warning: the module=Live&format=html&forceView=1&viewDataTable=VisitorLog&action=getLastVisitsDetails&small=1&idSite=2&period=range&segment=&widget=&showtitle=1&random=7448 request failed!

17

Is it the same as:

:question:

18

Yes, it is the same page I am having in problem with.

Using that page is doing a xhr POST to (https://www.domainname.com/matomo/index.php?date=previous30&module=Live&format=html&forceView=1&viewDataTable=VisitorLog&action=getLastVisitsDetails&small=1&idSite=2&period=range&segment=&widget=&showtitle=1&random=1939) which produces a 500 Internal Server Error.

produces not error
