My store displays this message every so often. A browser refresh will kill it, but it will return after a few more clicks. I'm running PHP 5.3.5 with 256MB of memory. Any advice will be helpful.
Here's a screenshot of the error: http://www.tonyfletcher.com/~pickup/Sites/filechute/tony_fletcher%202015-09-10_03-18-10_PM.jpg
Thanks in advance.
I'm assuming you've cleared all the Magento caches etc... - could you try clearing APC cache (if you use APC).
If you're not sure how to do this - you can create a PHP file and put the following in it; then run it in a browser (it won't output anything)
If that doesn't solve it - it might be worth having a word with your host.. it could be that you have a sick worker or something and a restart of the box may fix it.
