Question: I have a large database (about 244 MB+) and now I want to transfer it to other location from production to development server for fixing the bugs, upgrading and also backup. The hosting provider is Siteground.com

When I try to make a backup of magento database using magento backend Backup utility, phpMyAdmin or from Navicat for MySQL, unfortunately it fails each time showing no error.

I need Magento community help. What should I do to accomplish the backup successfully.

Any help would be greatly appreciated!

Answer: 
In my experience, I've come to find that Facebook does indeed cache the all the `<og:*>` tags the first time it's shared on Facebook. I ran into a similar issue when creating a "Share to Facebook" link on our website. I was trying to tweak the title and the description to be exactly how I wanted and I'd always have to change the knowledge base article I was working with to one I hadn't shared previously to see the changes I had made.

That being said, I have no clue for how long Facebook keeps that stuff in cache. I didn't do any sort of testing on that.
I don't know if this is a cache related problem. But the reason could rely in the fact that you are limited to change the og:title, you can do it before you reach the 50 likes, so I think that facebook keeps a history in case you try to change the title after the limit becomes reached.

Of course, this is only a supposition.
