Can't post ads, dropdowns linking to default permalinks. Please advise.
We cannot post ads on our site. In step one when posting an ad, where you select a category, after you select a category the page refreshes on a default permalink like example.com/?cat=10 instead of example.com/ad-category/automobiles/, thus showing a Whoops! Page Not Found.
The permalinks have been set to /%postname%/, we have restored to default pemalinks then turned back on the custom /%postname%/ and still no luck.
Please advise.
