Code being added to the end of my URLs

Have you tried:

– deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).

– switching to the Twenty Eleven theme to rule out any theme-specific problems.

– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.

This happened to me when I added ShareThis script to my header without using a plugin. I did that so that I could customize it.

I’m not sure what the hash is supposed to do, but they include the option automatically so I wouldn’t be surprised if removing it causes unexpected problems.

Hope that helps someone.

Before

doNotHash:false,
doNotCopy:false,
hashAddressBar:true

After

doNotHash:true,
doNotCopy:true,
hashAddressBar:false

ShareThis appends a hash to the URL to provide analytics on copy and paste events.

doNotHash turns on/off the hash tracking to your regular shares
doNotCopy turns on/off the feature to append a link to anything you copy that has the url included

hashAddressBar turns on/off the feature to append a hash to what is in your address bar.
