Broken Product Links

[rachelalbert]

For some reason, after doing some system upgrades, many product links on my site are broken.

The links that don't work, look like this:

The links that do work, look like this:

For some reason, the system is adding characters to the original URL rewrite and only then does the link work.

I already flushed the table called core_url_rewrite and reindexed Category URL Rewrites in the admin, but it doesn't seem to help.

I am running Magento V 1.9.2.2

How can I fix this?

For anyone with the same problem, here's what helped.

Was told to remove "Add This" as this would cause links to be configured that way.

It solved the problem.
