5.62 to 6.01
 

On the index.php, categories are not showing correctly (i.e. there's no links and just a jumbo of words). What went wrong?

Actually all the categories are showing messed up. But they are ok in the admin section. Very odd...

Never mind. I found the error of my ways. If this happens, just save the order of your categories (as mentioned in a previous post), and everything fixes itself.

Thanks!

Glad you got it all sorted. If there is anything else we can do to assist let me know.

I had the same problem after upgrading from 5.62. to 6.01 and the same fix worked for me as well! Thanks for the tip Longislandjam!
