Matomo 3.9.0 Errors

after auto upgrading to 3.9 in dashboard matomo

JSON.parse Error: "SyntaxError: Unexpected end of JSON input" in:

init @ index.php?module=Proxy&action=getCoreJs&cb=cff481c228a6d710970f4318d7abab8a:2774

not working:

  • schedule of last visits,
  • map of visits,
  • fonts in Russian are displayed incorrectly. Question marks show


Can you please delete everything in the /tmp directory? It seems like the JS hasn’t been generated correctly.

now try to empty the folder /tmp

delete everything? I have files in my temp folder:

  • .htaccess
  • index.php

and other folders

cleaned. still a mistake


It should be enough to delete everything in the assets folder.

But every file in /tmp can be regenerated.

it didn’t help. Error is not missing

In that case check the PHP error log for errors and try to open the index.php?module=Proxy&action=getCoreJs file directly, to see if there is anything in it.

And to be safe, also check if there is disk space left on the server.

the file opens
see the php logs

here is what I found

WARNING: /var/www/html/core/DataTable/Renderer/Console.php(152): Notice - Array to string conversion - Matomo 3.9.0 - Please report this message in the Matomo forums: (please do a search first as it might have been reported already)

never found a solution to the problem. Tell me?

After the last update everything worked
