Suddenly getting huge amout of error messages

Hi,

I’m running Piwik with Apache on a Windows 2008 Server and all of a sudden when I just call the piwik URL I get a browser full of error messages like the two samples below (literally hundreds of them, with variations of backtraces).

Environmental details:
PHP Version 5.4.24
Windows Server 2008 R2 Web Server Edition Service Pack 1
Apache/2.2.24 (Win32)


There is an error. Please report the message (Piwik 2.3.0) and full backtrace in the Piwik forums (please do a Search first as it might have been reported already!).

Notice: require_once(): apc_cache_find [-636667979] in D:\wwwroot\company\piwik\core\Loader.php on line 98

HELP!

restart the web server, this will clear APC cache which may fix this issue

Thanks - I deactivated the APC module, restarted Apache and now Piwik at least loads… but it is sitting there “loading widget” for ages.

can you setup: How to Set up Auto-Archiving of Your Reports - Analytics Platform - Matomo ?

PS: it would be better / faster to leave APC enabled but make sure you use latest version of APC and PHP as they are stable.

Maybe try and clear piwik temp folder, then delete and re-add widgets back in to dashboard.
