I am running the latest WP and have a Woothemes ecommerce theme installed. My hosting is VPS via Hostgator.
I have had problems or ages with the site crashing. Hostgator increased my PHP memory to 512 and that helped, but the site still crashes a few times each day.
The error only occurs when I link to the site using my Facebook and Twitter accounts. I use the Hootsuite Firefox plug-in on my browser to share the links to my social account, as soon as I do this the site runes really slow for about a minute and sometimes crashes altogether. The Hootsuite app is installed on my Mac browser and is not installed on the site or anything, so I don't understand why this happens?
Hostgator can't really help, so I was wondering if anyone else knows what is causing it.
Here are the installed plugins
W3 Total Cache
Thanks in advance
