Resolved - Error warning in Firefox browser

[Robin Somes]

Using CC6.05, Foundation skin, Product Addons plugin (legacy version 1.02)

In Firefox 35.0 and 38.0.1,

Go to the following page:

http://www.piscesconservation.com/cube/digital-downloads/analytical-software-full-programs/community-analysis-package.html

Select 1 copy of the add-on product "Introduction to Multivariate Statistics" from the SPECIAL OFFER section.

Click 'Add to Basket'.

Click 'View Basket'.

I receive the following error message: "Warning: filesize() [function.filesize]: stat failed for /export/home/clearwater/piscesshop/webs/www.piscesconservation.com/htdocs/cube/cache/6fbab.empties.cache in /export/home/clearwater/piscesshop/webs/www.piscesconservation.com/htdocs/cube/classes/cache/file.class.php on line 168"

The error is reproducible in Firefox; haven't encountered it in IE or Chrome.

Suggestions?

... and now I *have* just encountered it in IE 11.

This is not an error caused by the web browser.

PHP has a few filesystem functions that it keeps the results of in memory. It is called the 'statcache'. It remembers whether a file exists, its size, and maybe a few other facts.

What is unusual, though, is that there is code just above this statement generating the warning to clear the statcache.

I am also concerned that PHP is displaying errors such as this one. CubeCart has code to supress PHP from displaying errors.

In the meantime, we can try to edit the file /classes/cache/file.class.php, line 168:

Find:
$this->_page_cache_usage += filesize($file);

Change to:
$this->_page_cache_usage += @filesize($file);

Error message disappears. Thank you once again.
