Hey There, I appreciate the reply!
After messing around with it, I tried 3 separate goo.gl plugins and the problem still continued.
I ended up taking the plug ins out completely, and writing some code to check each article on load to see if it had a goo.gl shortlink stored in the postmeta table. If it didn’t have anything, it creates it. If the _googl_shortlink had reverted back to the default permalink, it fixes it.
It doesn’t stop the problem, but it does catch the results before they do any damage.
I think the culprit is the SNAP (social networks autoposter) plug in that I use to post to social media. It is the only other plug in I have that has an option to mess with shortlinks.
If you want to try the test environment with SNAP and see if you get the same results, feel free. At least then you’ll know what it is if anyone else runs both plug ins and has the same problem!
Thanks again!
