Posts does not show when slug="ad"

[sachirachin]

Recently I tried to add new post with already exiting categories, but each time I try adding the post, after I publish/ save it, it completely goes off the post list and I can't preview it on edit mode as well. After few duplicate posts, I noticed it it happens only when I add categories.

Then i tried to remove categories one by one and ended by noticing it happens when I add sub category with slug called "ad". Each time I try to add this category to a post, everything goes haywire. Then I renamed same category to "aad" and it started to work without any issue. I also tried other 2 letter slugs and it works without any issue.

Cannot reproduce. Maybe it's related to some plugins that you're using?

Oh, is it? Let me try disabling plug-ins I use.

Are you using any browser extensions to block ads and scripts?

@ocean90 WOW. Yes, it was the issue. I use ABP and after I disabled it, it started to work without any issue.
