There is nothing more frustrating than updating your site with the latest version of WordPress and then finding out that one of your plugins has stopped working because of a coding conflict. Then it is even more frustrating to find that the plugin has not subsequently been updated to accommodate the changes; that is, the revised version has not yet been released. But there is always help on hand, somewhere on the net, to get you out of trouble.
Upgrading to WordPress 3.5
Sharebar Plugin
If you have been using the Sharebar plugin, shown below and you have just updated to WordPress 3.5 then you might find that you have lines of code appearing at the top of your posts or page (on those that display the Sharebar).

If this is the case, then there is a simple fix but I am not going to take credit for it. The fix, and easy-to-follow directions, can be found here: How to Fic the Sharebar Plugin Issue after Upgrading to WordPress 3.5 Thanks to the author of this post for providing a very handy WordPress fix.
Backup WordPress
Remember, before doing any updates, you need to backup your WordPress blog or site. You can get help with this from my post on WordPress Backups here.
Future Updates to WordPress
As new upgrades are released, I will add, any needed fixes that I come across, to this post.
